Data element

the name of Johann August Arfvedson discovered a new element called lithium while he was working with a mineral petalite (Jefferson Lab Web). However, even though this element was found by Arfvedson, William Thomas Brande and Sir Humphrey Davy were the first people to isolate it (Jefferson Lab Web). Lithium is very abundant, it is a soft silver white alkali metal with the atomic number of three. Lithium is silver and contains no odor (Element Project). In addition to those features, lithium…

were the numbers that we had to produce in order to understand how and why there are many types of isotopes for each element. In doing this lab, we can think through the importance of finding the average atomic mass and not just using a single isotope for an element. 1. A weighted average must be used to calculate the average atomic mass of Beanium because, unlike a real element on the periodic table, the…

Introduction: This was an unannounced office safety inspection of this analytical x-ray registrant, which is located at 1927 Commercial drive, Port Allen, West Baton Rouge Parish, Louisiana. The registrant owns and operates one x-ray fluorescence (XRF) analytical x-ray unit, Thermo Fisher Scientific, model XL3t 980, serial numbers 92731, which is routinely utilized to perform alloy analysis of metals. This is the first inspection of the facility. One area of concern was revealed during the…

In the chemistry universe we have many different tools to differentiate and to help identify a substance. The smallest particle of matter is the atom. An atom has the same chemical particles as a whole sample of the element. Everything in the world is made up of these tiny particles called atoms. Growing on our knowledge of the atom, if you combine two atoms chemically you produce a compound. The two different classifications of compounds include organic compounds or those that contain carbon…

Lead, with its chemical symbol Pb, is a common heavy metal often utilized in many things. The chemical itself is toxic, heavy, and poisonous. Its natural form is a soft and malleable metal with blue-gray color. Lead can be man-made or found in nature, most can be obtained from ores. Even though lead is such a common metal on this planet, it only makes up 0.0013% of the Earth’s crust. Lead is easily mined or made by roasting galena in hot air, which is mostly made of lead sulfate. Lead was…

According to Encyclopedia Britannica in Britannica School the word tungsten comes from the mineral scheelite which was once called tungsten, which means heavy stone. The name comes from the Swedish chemist and his countrymen who discovered the metal in scheelite. The atomic number of tungsten is 74 and tungsten’s atomic weight is 183.84. Tungsten is also one of the densest and hardest metals in the world. From Encyclopedia Britannica in Britannica School, tungsten was discovered by a Swedish…

Lead is an element that naturally occurs in the environment, but much of the lead found in the environment today exists as a result of human activity. When young children are exposed to lead, it can enter the bloodstream and cause a myriad of negative health effects that can affect them for the rest of their lives, as the consequences of lead poisoning are often irreversible (National Center for Healthy Housing, 2008). Based on a child’s level of exposure, they could experience hyperactivity,…

Dmitri Mendeleev is the creator of the first periodic table. Dmitri was born on February 8, 1834, in Verkhnie Aremzyani, Russia to a family of 16. His dad was a teacher, who went blind. His mom ran a glass factory. At the age of 13, his dad died. Dmitri decided to go to college when he was 16. He applied to the same college his dad went to, and was accepted partially because they knew his dad. He studied to become a teacher there. When he was 20, he graduated at the top of his class. Then,…

Final Hours What would you want to do if you only had twenty four hours left to live. For my last twenty four hours, I would spend with my brothers; Bryce, Weston and Quinn, since we all love to go off-roading I would go buy jacked up mud racing trucks and tear up our favorite minimum maintenance roads around the outskirts of Humboldt. The reason I chose to bring my three brothers is because they all love to do some type of off-roading, so I thought they would be part of my last day. I chose…

Toxicology Profile; Arsenic Basic Chemistry Introduction Arsenic is an abundant naturally occurring element with an atomic number of 33 and an atomic weight of 74.92 g. Although strictly a metalloid, arsenic is commonly referred to as a ‘heavy metal’ and can be found within group 4 of the periodic table. It should be noted that most of the other elements within this group have a biological role, but arsenic itself is a toxin (see section 1.x). Some additional chemical properties of elemental…
