Abundance of the chemical elements

Xenon is one of the 6 noble gases on the periodic table belonging to group 18. The element was discovered by Sir Ramsay in 1898. Xenon’s symbol is Xe and its atomic number is 54. Xenon’s atomic mass is 131.293 grams. Its boiling point is -107 degrees Celsius, while its freezing point is -112 degrees Celsius. The density of Xenon at 20 degrees Celsius is 0.005887 grams per cubic centimeter. Xenon has 21 isotopes Xenon is described as being completely colorless and odorless, however when…

Atomic theory developed 2,500 years ago and evolved around the question whether or not something could be divided into forever. Greek philosophers debated this subject a lot, especially one name Democritus. He believed that something would only be able to be divided to a certain point because matter consisted of atoms and atoms are indestructible. Aristotle, however did believe something could be divided forever and did not believe in atoms. With all this controversy, one would expect an atom…

Cyclic Voltammetry of Ferricyanide Analytical Lab 1: 2410L Benjamin A. Battiste Group 2 10/14/15 Introduction: The purpose of this experiment is to use cyclic voltammetry to see how ferricyanide can be reduced to ferrocyanide. Using cyclic voltammetry a calibration curve will be created to determine the concention(mM) of an unknown solution of ferricyanide. In cyclic voltammetry, the potential of a substance is scanned starting from a certain voltage, going to another voltage, and then…

The light in neon signs are made of neon gas placed into glass tubes bent into decorative designs. Neon is used very often because it as a noble gas. This is because the every atom has an electron shell, therefore the atoms do not react with other atoms and it becomes very difficult to remove an electron because it would take much energy. When a high-voltage electrical current passes through the neon gas, its energy can remove an electron. The atoms in the tube are moving around and hitting…

1) Petcoke is the nickname given for Petrolum Coke, a material that looks like coal and is a byproduct of refining the oil brought in from Canada. (Chicago Public Health) While no known illnesses of health effects are associated with Petcoke, they can cause breathing issues, which includes “coughing, wheezing, or shortness of breath.” (Chicago Public Health) Currently, the Illinois Environmental Protection Association Agency is investigating an open-air storage area along the Calumet River (EPA)…

The guiding question is that which changes are examples of a chemical change and which are examples of a physical change? Our claim is that 100ml water mixed with salt paraffin wax melting are examples of physical change. While magnesium strip heated, sodium hydroxide and copper chloride mixed and hydrochloric acid added to sodium bicarbonate are chemical change. For task 1, we measure 100ml of water, weigh 5g of table salt and mix the 5g of salt and 100ml of water. Stir until change is seen.…

Kiley Kern English 4 Mrs.Sites February 23, 2017 The Good Earth and the Virtuous Woman Olan and the Virtuous Woman are two very much alike women that are exceedingly alike considering the sustained laborious work that they perform in order to provide for their families. Neither Olan or the Virtuous Woman expect or need to be nurtured, they are consistently showing the people around them, their capability of remaining physically and mentally strong despite any obstacles or hardships that come…

goddess of greek mythology. Titanium has 22 protons, 26 neutrons, and 22 electrons. The atomic number of this element is 47,867. Titanium is a lustrous transition metal. William Gregor was a man who was interested in minerals. He recognized the presence of a new element. The boiling point for this element is 5,948 fahrenheit and the melting point is 3,034 fahrenheit. The titanium chemical properties is more reactive at high temperatures. It can actually catch fire when heated in the presence of…

many foods or dietary supplements. The mineral zinc is found in the periodic table with the symbol ZN and has an atomic number of thirty. Zinc is one of the more abundant elements in the Earth’s crust, the twenty-fourth most abundant, and it contains five stable isotopes. This mineral is also known as an essential trace element, meaning the human body only requires a small amount to be considered healthy. One of the health benefits of zinc includes boosts in the immune system, by fighting if…

You think summer is hot, think again. Although copper is a common metal known to man, there may be a few interesting details that you did not know about the element. Such as how hot you must heat copper before it melts into liquid form, or how the smallest dose of copper could make a major impact on your health. The uses of this metal could open up new opportunities and inspire new innovations that may have not been thought of before. Copper dates back almost ten thousand years and has been a…
