The Element Argon
The Element Argon Argon Argon was originally named after the Greek word “Argos,” meaning inactive. Argon’s chemical symbol was just A before it was changed to Ar in 1957. It has an atomic number of 18, and is in Period 3, Group 18. Argon contains 18 protons and 18 electrons with 22 neutrons. It has an atomic mass of 39.948.
Suspected to be present in the atmosphere in 1785 by Henry Cavendish, Argon wasn’t actually discovered until 1894 by William Ramsay, a Scottish chemist, and Lord Rayleigh, an English chemist. Argon makes up about 0.93% of the Earth’s atmosphere. It is a byproduct of the product of nitrogen and oxygen. Per year, it is commercially produced around 700,000 tons globally.
Argon is a colorless, odorless, tasteless noble gas. Although it is colorless, argon gas does produce a pale blue-violet light when a little mercury is added. It has a melting point of 83.30 K (-189.35 C or -308.83 F) and a boiling point of 87.30 K (-185.85 C or -302.53 F). Even though argon isn’t toxic, it still can be harmful if it enters the body. If inhaled, it can cause dizziness, dullness, headache, and suffocation. If it enters through the skin and it comes in contact with liquid, it can cause frostbite. If it gets in the eyes and it comes in contact with liquid, it can also cause frostbite. The gas is an asphyxiant, due to it not supplying the body with oxygen, and can cause suffocation. Air is 25% less dense than argon, so it is considered very dangerous in sealed spaces. In closed areas, it was found to cause death because of it being an asphyxiant. An example of this situation would be an event in 1994, where a man was asphyxiated. He entered an argon filled section of oil pipe under construction in Alaska. Since argon is colorless, odorless, and tasteless, he had no idea that he walked into his demise. The incident exhibits the risks of argon tank leakage in confined

    But element 85 gives our study a greater depth than has yet been revealed by the already covered elements. What this story shows is that the nationalistic prejudices persist to this day in many respects and that the identity of the “discoverer” of the element very much depends on the nationality of the textbook that one might consult. It is also an element for which the majority of sources give an incorrect account in declaring Corson, MacKenzie, and Segrè as the true discoverers. The account I will detail owes much to the recent work of two young chemists, Brett Thornton and Shawn Burdette, whose 2010 article I have drawn heavily from.…

    BIOLOGY STUDY GUIDE CHAPTER 4– THE CHEMICAL BASIS OF LIFE Matter = anything that takes up space and has mass (major types of matter = solid, liquid, and gas) Any type of matter is made of one or more elements. o Element = a substance that cannot be broken down into other substances by regular chemical processes. (examples: gold, silver, mercury, etc.) There are approximately 25 elements necessary for life. • Examples: oxygen, carbon, hydrogen, nitrogen, calcium, phosphorous, etc. • Trace elements = those elements that make up less than 0.01 percent of your body mass (examples: iodine, iron, copper, etc.) Compounds = a substance containing two or more elements; these elements are always present in this compound in the same ratio o For instance, water is a compound where hydrogen and oxygen are combined. The ratio of hydrogen to oxygen in water is always 2:1. (Remember that the chemical formula of water is H2O.) o Compounds have different characteristics than the elements that make them up. (Water is liquid at room temperature, but when hydrogen and oxygen are by themselves, they are gases at room temperature.) Atoms = smallest possible piece of an element o A better definition of an atom may be: the most basic unit of matter that cannot be broken down into smaller pieces by ordinary chemical methods. o This can be confusing, because when you read the above definition or when you start looking at the periodic table in class, is oxygen an atom or an element? o An element is essentially the same as an atom. Why do we bother with two different words? • An element is the most common version of an atom. The element you see on the periodic table for oxygen is the most common version of the oxygen atom that exists in nature. There are several different kinds of oxygen atoms (with different numbers of neutrons than the one found on the table), but they are not as commonly found in nature. All atoms are made of even smaller…
