Atom

The element I selected for the Element Research Project is Osmium. Osmium’s chemical symbol is Os. Osmium’s atomic mass is 190 amu. Osmium’s atomic number is 76, it has 76 protons and 76 electrons. Osmium also has 114 neutrons. Osmium belongs to the transition metal group in the middle of the periodic table. Osmium’s Bohr model with electric configuration has two electrons in the first shell, eight in the second shell, eighteen is the third shell, thirty two in the fourth shell, fourteen in the…

In this work, we assume two different potentials for the initial and final heavy quarkonia and the intermediary hybrid states. The most popular potential form for the study of heavy quarkonia is the Cornell potential [11] V(r)= -κ/r + b r (2.13) Usually many authors prefer α_s (r) instead of κ. The relation between them is κ=(4α_s (r))/3 and α_s (r) can treated as constant for bb ̅ and cc ̅…

Ref: Saunders N. 2000, Creative Chemistry You have seen that the Group 1 alkali metal elements increase in reactivity as you go down the group. Sodium is less reactive than potassium, which is less reactive than rubidium (which you weren’t allowed to observe directly!) Today, you will use displacement reactions to work out the order of reactivity of the Group 17 halogen elements using chlorine, bromine and iodine. Hypothesis: The higher on the periodic table the more reactive the element…

Salbutamol Discovery Chiral chemistry was introduced in 1848 by French chemist and biologist, Louis Pasteur. He discovered this new branch of chemistry after he separated two isomers of ammonium tartate (1). This paved the way for several progressions in the pharmaceutical industry. Although it took approximately a century for scientists to use chiral compounds as effective drugs, they have played a remarkable role in the life of plants and animals (1). The credit for discovering the chiral…

ii. Non-Acidic Oxygen Compounds Figure 3.4 Isomers of non-acidic oxygen compounds (Retrieved from Chemistry of Petrochemical Processes, 2nd Edition, 2001). C .Asphlathenes It is organometallic compounds and inorganic salts (metallic compounds). Mostly sodium, calcium, magnesium, aluminium, iron, vanadium, nickel are present either as inorganic salts, such as sodium and magnesium chlorides, or in the form of organometallic compounds, such as those of nickel and vanadium (as in porphyrins).…

Carbohydrates are biological molecules made up of organic substances such as Oxygen, Hydrogen and Carbon (Rapidlearningcenter.com 2015). They normally have a two to one hydrogen to oxygen ratio and can be classified by the empirical formula Cm (H20)n where m and n could be possibly different. Some biologists refer to carbohydrates as hydrates of carbon and they are technically correct. Alternately, there is no possible empirical formula that can describe lipids. Lipid must be identified…

Luis Miramontes was a famous Mexican chemist who invented birth control. He was born in March 16, 1925 at Tepic, Nayarit. His full name is Luis E. Miramontes Cardenas. At the National Autonomous University of Mexico, he received his first degree in chemical engineering. He was a researcher at the National Autonomous University of Mexico in the Institute of Chemistry. He also was the faculty of chemistry there. Not only that, but he was the director and professor at the Universidad…

In 1817 a scientist known by 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…

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…
