Abundance of the chemical elements

The Periodic table is a table that organizes the different known elements, and Neon is one of those elements. Neon is an element that is a non-metal and also a noble gas. The start of the element, Neon, was when a Scottish chemist named William Ramsay discovered Neon, Krypton, and Argon, which are all noble gasses ("Periodic Table of Elements: Los Alamos National Laboratory." Periodic Table of Elements: Los Alamos National Laboratory). For this achievement, William Ramsay won the Nobel Prize in…

Neon is one of the world’s rare and most expensive elements. I chose Neon because of it's uniqueness. In 1898, William Ramsay and Morris Travers at University College London isolated krypton gas by evaporating liquid argon. They had been expecting to find a lighter gas which would fit a niche above argon in the periodic table of the elements. They then repeated their experiment, that time allowing solid argon to evaporate at a slow pace under reduced pressure and collected the gas which came off…

The second most abundant element in the Earth’s crust other than oxygen is silicon which if by mass is around 25.7g or 23%. However in nature, silicon never exist as a free or pure element but instead it mostly combines with the most abundant element in the Earth’s crust, oxygen, hence producing silica (SiO₂) or silicate minerals. The most prominent charge of Si in the crust is +4 rather than +2 which involve a silicon atom to bond in a tetrahedral manner with 4 other oxygen atoms giving rise to…

embedded in a matrix are most often found in the famous spanish mines. http://www.minerals.net/mineral/pyrite.aspx Pyrite’s chemical formula is FeS2, which is the same as the much rarer mineral, Marcasite. Even though these two have the same chemical formula, they both crystallize differently, causing them to be classified as different minerals. Sharing the same chemical formula causes these two minerals to be mislabeled, since their physical characteristics are so similar, and the only real…

drastically changed over time. What we know as an atom today is composed of many subatomic particles. There is a positively charged center in an atom called the nucleus, which contains protons and neutrons (Doc. 3). The number of protons determine what element the atom is, and the number of neutrons influences the atom’s mass. There are also negatively charged particles, called electrons, to counteract the positive charge of the nucleus. These electrons fly around the atom’s empty space, which…

Chapter 11, “The Chemical Elements”, was of great interest to me. “Chemistry is the study is the study of the composition and structure of matter (anything that has mass) and the chemical reactions by which substances are changed into other substances (James T. Shipman 285).” In this summary paper, I will discuss some of the highlights of the chapter. The way I see it, God is the original/first chemist. He took His own creations (the elements in our Periodic Table) to make provisions for…

contains a molar mass of 79.904 grams per mole (g/mol). Bromine falls within group 7 of the periodic table and is a halogen. Its atomic number is 35 and is one of seven diatomic elements. Bromine is one of two elements that holds the natural state of liquid. I chose bromine for my independent paper because of many other elements I knew little to none about, I have never heard of bromine and was interested to learn more. The bromine name was derived from the word bromos, meaning “bad smell” or…

Oxide, on the rate of hydrogenation of ethenol (vinyl alcohol). Introduction Notongooglenium Notongooglenium is a newly discovered element with an atomic number of 24.5. Due to its placement on the periodic table between Chromium (24) and Manganese (25), it is believed to have a similar atomic and electronic structure to these two elements, and hence similar chemical properties. This means that Chromium or Manganese can be used…

Back on the date of June 18, 1773 Joseph Priestley was in his science lab exploring and studying about the elements. Priestley had done a lot of experiments to find more about the element now known as oxygen. The first experiment dealt with using the previous methods Carl W. Scheele used. Carl W. Scheele was a chemist from sweden, but in his discovery of oxygen he had other people helping him throughout the process. Joseph had thought in his mind, “ If I can do this scientific inquiry on my own,…

The element Titanium is a very light metal and it’s in the periodic table group 4. This element is a transition metal and the symbol is Ti. The color of titanium is a silver grey and white color. The atomic mass is 47.867 and atomic number is 22. This element however is resistant to chlorine, and sea water. It has 22 electrons, 22 protons, and 26 neutrons. The density is 4.54 The discoverer who found titanium is William Gregor a Mineralogist. The year it was discovered was in 1791. Where it had…
