Helium is the second element in the periodic table. Its period number is 1 and it is apart of group number: 18. The group that Helium falls under is the Noble Gases. The element has an atomic number of 2, an atomic mass of 4 and is classified as a non-metal. It is the second most abundant element in the universe. Helium was discovered on the sun before it was found on the earth. In 1895, Pierre-Jules-César Janssen, a French astronomer and Norman Lockyer, an English astronomer both who discovered…

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 His ultimate creation, mankind. He made oxygen for use to breathe. God combined hydrogen and oxygen, in the right combination, to create water. He left precious metals like gold and silver for mankind’s use, and all of the other elements. The…

Neon is the 10th element on the periodic table. It was discovered by Sir William Ramsay and Morris Travers in 1898 (Mowat 130). It has 10 protons, 10 neutrons, and 10 electrons. Neon has no stable compounds because it is a noble gas. However, there are three stable isotopes, the most abundant being neon-20 (90.5%). It has no color, odor, or taste. It changes from a gas to a liquid at -245.92°C and from a liquid to a solid at -248.6°C (Chemical Elements). It is found in the sun and the…

Reflection Paper Being completely undecided in my career path, and since I have taken all of the available chemistry classes, when the opportunity to job shadow a water operator at the Emlenton Water Treatment Plant arose, I took advantage of it. Even with my knowledge in chemistry, I went into the experience knowing only that they use chemicals, such as chlorine, to treat the water from the river. I came out of the experience with a more selective career path and a much greater knowledge and…

the hydrogen and carbon molecules from dietary fats, proteins, and carbohydrates are mixed with oxygen to form carbon dioxide and water as energy is released. These end products that are produced during aerobic metabolism are to some extent harmless and simply eliminated from the body. The citric acid cycle, sometimes called the Krebs cycle, provides the final common pathway for the aerobic metabolism of nutrients. The electron transport system is where oxidation of electrons from the hydrogen…

structure of perbromate is a tetrahedral. Although the structure contains 32 valence electrons, it obtains a total 1 single bond and 3 double bonds. The oxygens in the Lewis structure follow the octet rule however bromine does not. Bromine (besides hydrogen) does not follow the octet due to certain exceptions. Bromine can also found in the Earth’s crust. It is an acidic element and can be harmful and cause irritation if encountered. Bromine vapor, if exposed to, can be fatal even over a short…

Introduction The Objective was to determine the mass percent composition of the mixture using a chemical reaction and stoichiometry mixture Na2CO3 and NaHCO3. To do the lab by using the constant mass. Constant mass is a quantitative chemistry technique where a single chemical species or group reactants is heated with constant weighing until the mass does not change. After heated the Na2HCO3 will undergo a decomposition and Na2CO3 will not undergo reaction. The balanced equation is…

reflecting the 4 distinct types of hydrogen. The area represented by the 4 peaks was 10, which…

Prac 18 – Reaction Rate of Notongooglenium – Angus Dally Research Question: How does the presence of a Notongooglenium oxide catalyst effect the rate of hydrogenation of ethenol (vinyl alcohol)? Aim The aim of this experiment is to find the effect of the manganese oxide catalyst, a similar compound to Notongooglenium 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…

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,…
