10 Lead Element Facts (Pb or Atomic Number 82)

Lead is a heavy metal you encounter in everyday life in solder, stained glass windows, and possibly your drinking water. Here are 10 lead element facts. Fast Facts: Lead Element Name: LeadElement Symbol: PbAtomic Number: 82Atomic Weight: 207.2Element Category: Basic Metal or Post-Transition MetalAppearance: Lead is a metallic gray solid at room temperature.Electron Configuration:  [Xe] 4f14  5d10  6s2  6p2Oxidation State: The most common oxidation state is 2, followed by 4. The 3, 1, 1-, 2-, and 4- states also occur. Interesting Lead Element Facts Lead has atomic number 82, which means each lead atom has 82 protons. This is the highest atomic number for the stable elements. Natural lead consists of a mixture of 4 stable isotopes, although radioisotopes also exist. The element name lead comes from the Anglo-Saxon word for the metal.  Its chemical symbol is Pb, which is based on the word plumbum, the old Latin name for lead.Lead is a considered a basic metal or post-transition metal. It is a shiny blue-white metal when freshly cut, but oxidizes to a dull gray in air. It is a shiny chrome-silver when melted. While lead is dense, ductile, and malleable like many other metals, several of its properties are not what one would consider metallic. For example, the metal has a low melting point (327.46  oC)  and is a poor conductor of electricity.Lead is one of the metals that was known to ancient man. It is sometimes called the first metal (although the ancients also knew gold silver, and other metals). Alchemists associated the metal with the planet Saturn and quested for a way to transmute lead into gold.Over half the lead produced today is used in lead-acid car batteries. While lead does occur (rarely) in nature in its pure form, most of the lead produced today comes from recycled batteries. Lead is found in the mineral galena (PbS) and ores of copper, zinc, and silver.  Lead is highly toxic. The element primarily affects the central nervous system. It is particularly dangerous to babies and children, where lead exposure can stunt development. Lead is a cumulative poison. Unlike many toxins, there really is no safe exposure level to lead, even though it is present in many common materials.Lead is the only metal which exhibits zero Thomson effect. In other words, when an electrical current is passed through a sample of lead, heat is neither absorbed nor released.While modern scientists can readily distinguish most elements, it used to be difficult to tell lead and tin apart because the two metals share so many similar properties. So, for a long time the two elements were considered to be different forms of the same metal. The ancient Romans referred to lead as plumbum nigrum, which means black lead. They called tin plumbum candidum, which means bright lead.Wood pencils have never actually contained lead, even though lead is soft enough it could be used for writing. Pencil lead is a type of graphite the Romans called  plumbago, which means act for lead. The name stuck, even though the two materials are different. Lead is, however, related to graphite. Graphite is a form or allotrope of carbon. Lead belongs to the carbon family of elements.There are countless uses for lead. Because of its high corrosion resistance, the ancient Romans used it for plumbing. While this sounds like a dangerous practice, hard water forms scale inside pipes, lessening exposure to the toxic element. Even in modern times, lead solder has been common for welding plumbing fixtures. Lead has been added to ga soline to reduce engine knock, to face paints and paints used for toys and buildings, and even in cosmetics and foods (in the past) to add a sweet flavor. It is used to make stained glass, leaded crystal, fishing sinkers, radiation shields, bullets, scuba weights, roofing, ballasts, and statues. While once common as a paint additive and pesticide, lead compounds are less commonly used now because of their lingering toxicity. The sweet taste of the compounds makes them attractive to children and pets.The abundance of lead in the Earths crust is  14 parts per million by weight. The abundance in the solar system is  10 parts per billion by weight.

Family Systems Differ from Home to Home Essay - 768 Words

Everyone has an ideal view of what a family system should be and how it should be ran. However in today’s society it is very difficult to always follow what others think due to the lack of love and trust within individuals who decide that in the moment a family is what they want until the time comes and a family is not what they can handle. As a young child, I grew up with both parents, and thought that life was superb. However things did not last long and I soon was a product of a single parent home. Now for me double parenting and single parenting did not have much effect on me growing up but now I so desire for a family where I have a husband and he is there not only as my husband but a father, a provider for our family, and a†¦show more content†¦For example growing up as a child, my family comprised of my mom, dad, grandma, grandpa, and uncle (my mom’s brother) all living under the same roof. Everyone in the family played a part and understood what th eir role was. The men in the family took care of things such as taking out the trash, occasional cleaning, in the winter they would bring in firewood, and take care of any handiwork that needed to be done. As far as the women, they always went to the grocery store; they took care of the children, prepared meals, and did most of the cleaning. It was what worked for us. Now when my mom got her own home and my dad came along with us (they were never married), the balance in my grandmother’s house was off. There were fewer mouths to feed and less hands helping with the work that needed to be done. It was an odd and awkward time for us but we were able to start our own homeostasis. The family system worked totally different at my mother’s home. My mother was the breadwinner and my dad was the â€Å"stay at home dad† and he took care of the housework and me while my mom worked. Either way it still worked out though it was not the same as at my grandparentâ₠¬â„¢s home but everyone was still able to play a part which did not through off our balance.

Personal Branding Website 5 Tips to Help You Nail Yours

Branding is key, regardless of your websites focus. It doesnt matter if youre running a blog, an online store, or a service site – your brand will play a significant role in the way visitors perceive you, so its important to start developing it as soon as possible. Thats where a personal branding website comes into play.With a powerful brand, people may begin to recognize your content simply by seeing your logo or your sites other imagery. This kind of recognition is fantastic because it means that your audience knows and trusts you. As a result, youre likely to have fewer problems attracting conversions.In this article, were going to talk a little about what online branding is and the role your site plays in it. Then well cover some tips for building a personal branding website using WordPress. Lets begin! , tagline, colors, and style are all pieces of its brand. In other words, your online brand is a combination of all the elements that people associate with your website and other presences (such as your social media profiles).If you think about it, most popular websites have easily-recognizable branding.Take this logo, for example:Were willing to bet you know exactly what service this icon represents, even without seeing it in context.A powerful online brand can make your website more memorable and engaging, which is crucial for building an audience and driving conversions. Of course, branding alone is not enough – youll still need to create and publish engaging content if you want your personal branding website to succeed. If you pair both of those elements together, youll have a winning combo on your hands.Five tips for creating an effective personal branding websiteBranding, in most cases, is all about implementing a few key elements. In the next several sections, well talk about what those elements are, and how to use them to develop an effective personal branding website.1. Design a unique logo that reflects your brandWhen it comes to onli ne branding, your logo is the element that stands out most. A unique logo can set you apart from the competition and make your website and content easier to recognize. Not taking the time to create (or commission) one is a wasted branding opportunity.The problem is that not everyone has the design chops to create a stylish logo. In some cases, hiring a designer to do this for you will be your best option. Of course, youll need a decent budget if you want a logo that doesnt look like it was put together in five minutes.Whether you decide to design a logo on your own or hire someone to do it, there are a few things youll need to keep in mind:Your logos concept should reflect what your site is all about.It should be easy to read and/or understand quickly.It should include your brand colors (well talk more about this element in a moment).To play it safe, we recommend that you commission multiple logo variations, so you can weigh your options and choose the one that represents your brand perfectly. While youre at it, you might also consider developing a tagline that describes what your brand is about, as this is an excellent complement to a strong logo.2. Choose a color palette for your websiteIn some cases, users learn (usually subconsciously) to associate specific colors with a particular site. When you think about Facebook, for example, you can probably picture the exact shade of blue the company uses throughout its website and other materials.Thats not a coincidence, either. That association forms because those sites make color a deliberate part of their branding strategy. To do the same, youll need to choose a color – or multiple hues – and incorporate them into as many elements of your site as you can.Choosing a palette where each color complements the others can be tricky. However, using a color wheel  can make the process significantly easier. For best results, youll want to stick with somewhere between one and three primary colors.As for wh ich elements to use your brand colors on, there are plenty to choose from, including:Buttons and Calls To Action (CTAs)Navigation bars and footersDividers between sectionsFeatured imagesThose are just a few places to start, of course. You can get pretty creative when it comes to incorporating your brand colors into your designs. Just keep in mind that consistency is critical, which brings us to the next section.3. Keep your branding consistent throughout your websiteFor a personal branding website to work, it requires a high level of consistency. That is to say, your branding elements should appear throughout each page, and should look uniform.To give you an example, you wouldnt want to use two different logos within the same website, since that could easily lead to confusion. The same logic applies to all other aspects of your branding, from the colors you use, to which elements you apply those colors to.This also means that if you use a particular color for CTAs on one page, its b est to do the same on other relevant pages. The goal is for users to become acquainted with your brands core elements, so theyll recognize them more easily over time.4. Add social icons to your websiteThese days, just about every website needs a social media presence. Moreover, those social media accounts should also represent your online brand. That means using the same logo, colors, and tagline, as well as writing in the same style as your sites content.Keep in mind that you dont need social media accounts on every platform, just those that are relevant to your audience. Then youll want to link those accounts to your WordPress website, and the best way to do that is by using social icons.The WordPress community offers a lot of plugins you can use to achieve this. One of our favorites is called Social Icons Widget: Social Icons Widget by WPZOOM Author(s): WPZOOMCurrent Version: 3.4.0Last Updated: October 5, 2019social-icons-widget-by-wpzoom.zip 98%Ratings 674,802Downloads W P 4.3+Requires This plugin includes icons for over 80 social media websites (yes, there are that many of them!). Plus, it enables you to add any of them to your pages using widgets. This will direct your website visitors towards your social pages, where theyll be exposed to more of the same branding – hopefully helping it to stick more effectively.5. Create an About Us or About Me pageIf you want people to connect with your online brand, they need to know what its all about and what you or your business stands for. The easiest way to share this information is by adding an About Us section or page to your website:About Us pages dont need to be overly complicated. In most cases, a few pictures of your team or headquarters alongside a brief introduction will do the trick. The idea is to give visitors enough information that they know youre more than just a personal branding website, and there are real people behind the content you publish.There are plenty of ways you can go abou t creating an About Us page in WordPress. Some themes include pre-built sections or pages that are perfect for these purposes, including several of our own. So you may want to  check those out and see which one is a good fit for your site.Go to topConclusionChances are high that a lot of your favorite websites have powerful online branding. Youd probably be able to recognize their names and logos anywhere. Your goal is to use your website to develop your online brand in much the same way, until it reaches the point where you dont need to introduce yourself anymore.Lets review some of the ways you can develop a personal branding website from the ground up:Design or commission a unique logo that reflects your brand.Choose a color palette for your website.Keep branding consistent across all your pages and content.Add social icons to your website.Create an About Us page.
