Abundance of the chemical elements

*Both the communities of Shoal Lake 40 and the land surrounding the Marlin Mine have been environmentally affected which also affects the health of locals. In the surrounding areas of the Marlin Mine, there have been many complaints by locals that the water is being contaminated by toxic metals (Zarsky and Stanley 2013). Research encourages that there is this heightened level of metal in the river close to the mine, which puts the ecosystem and human health in danger (North and Young 2013).…

My element Sulfur is the most important element there is. The symbol for Sulfur is S. An yellow looking odorless substance that is found underground. Sulfur has an atomic number of 16, atomic weight of 32.065. The element Sulfur is classified as a non-mental with the boiling point of 832.28 degrees Fahrenheit and a melting point of 239.38 degrees Fahrenheit. There are several mixture of sulfur compounds, including the mineral pyrite, or iron sulfide. Each of these types of Sulfur plays its own…

Properties; Beryllium is a toxic bivalent element; with a steel gray metallic look to it. Beryllium is also a durable, lightweight element. Primarily used as a hardening agent in alloys. It has one of the highest melting points of the light metals. With the atomic number of 4, and being classified within the group of alkaline earth metals. The element is nonmagnetic and resists oxidation when exposed to air at standard temperature and pressures. It’s also found in over 30 different minerals; for…

are some risks, the reward undeniably outweighs them. Iridium-192 has a half-life of approximately 73 days, and it decays into Platinum-192. This is because radioisotopes undergo radioactive decay, which means they slowly break down because the element has an unstable nucleus. During Iridium-192’s decay process, it undergoes a nuclear change, transforming…

To start we will be looking at blood’s role in distribution of lead. Blood plays a major role in the distribution of lead even though it has a tendency to carry a small fraction of the total amount of lead present in a body. This is due to the fact that blood is constantly circulating and coming into contact every single part of the human body. Lead found within the blood system on average has a half life nearing only 1 month. Next is distribution and storage through the accumulation of many…

being in an s, p, d, or f orbitals. The number of protons in an atom being called the atomic number. The mass number is the same number of particles in the nucleus. Leucippus then had the thought that everything in the universe was made up of elements that could not be broken down. The term atomon was used to describe how atoms could not be…

The words nutrient and nourish are both derived from the Latin word nūtrīre which means ‘to feed, nurse, support and preserve.’ In other words, it’s really important to nourish your body with the right nutrients to support and preserve your health. While plants get their nutrients from the soil, we get ours from the foods we eat. Yet many of us don’t consider whether or not the foods we put into our bodies are full of healthful nutrients or not. We’re more concerned with taste and if we can…

Theory on Lithium in Stars May Be Confirmed The light chemical element lithium is one of the few elements that is predicted to have been created by the Big Bang, 13.8 billion years ago. But understanding the amounts of lithium observed in stars around us today in the Universe has given astronomers headaches. Most heavy elements are produced during supernovae, as massive stars explode in their death throes. However, these events were believed to be too rare to produce the vast amount of…
