![]() ![]() A man died in 1984 from asphyxiation due to argon at the construction site of an oil pipe in Alaska. It is difficult to detect and creates concern for argon tank leakage into confined spaces. It can also act as a preservative as it replaces oxygen within a bird.Īrgon can be dangerous to humans in closed areas. This makes it useful to asphyxiate birds as a more humane form of slaughter. Argon Applications in Today’s World What is Argon Used For? Poultry IndustryĪrgon is 38% denser than air and displaces oxygen near the ground. Argon shares similar properties with its group. ![]() ![]() Other noble gasses include helium, neon, krypton, xenon, and radon. Argon’s electron configuration is 3s2 3p6. Argon is a noble gas with a full valence electron shell, making it unreactive.Īrgon has an electronegativity of 0 (Pauling Scale). This element is the third most abundant gas in Earth’s atmosphere. Argon glows a violet and lilac color in a gas discharge tube.Īrgon, atomic symbol Ar, has an atomic number of 18, and lies in group 18, on the periodic table, below neon and to the right of chlorine.Scientific research uses argon to search for dark matter.The atmospheres of Mars and Mercury contain argon.Argon was the first noble gas to be discovered.Here is a new study on the effects of inhaled argon on brain injuries in mice. Argon is being researched as a cheaper alternative to xenon in the treatment of brain injuries.Blue neon lights actually contain argon.They used to be preserved by helium, however, it was replaced because it would leak from the case and require replacement. The American National Archives preserve the Declaration of Independence and the Constitution with argon.The word argon is derived from a Greek word meaning “lazy” and “inactive.”.Argon is twice as abundant as water vapor and over 20 times as abundant as carbon dioxide.It is commonly used for industrial purposes, in scientific research, and as a preservative. It is the most common noble gas and is chemically inert. Not to miss out, element 102, Nobelium, No, is named in honor of Alfred Nobel, who set aside his vast fortune to establish Nobel Prizes.The element argon is colorless, odorless, nonflammable, and nontoxic. Mendeleev never received a Nobel Prize for his work, but element 101 was named Mendelevium, Md, after him. For instance they discovered phosphorus when they isolated it from urine. Over time these gaps have gradually been filled in as scientists unearthed new elements. Not only did Mendeleev arrange the elements in the correct way, but he also had the foresight to leave gaps for undiscovered elements. At that time, he had only 50 elements to arrange. He wrote the properties of the elements on pieces of card and rearranged them until he realised that, by putting them in order of increasing atomic weight, certain properties of elements regularly occurred. Then in 1869, a Russian scientist called Dmitri Mendeleev produced one of the first practical periodic tables. Several other attempts were made to group elements together over the coming decades. The earliest attempt to classify the elements was in 1789, when Antoine Lavoisier grouped the elements based on their properties into gases, non-metals, metals and earths. The discovery of other elements followed regularly and soon it became necessary to arrange them in some sort of order. However, the first scientific discovery of an element occurred in 1649 when Hennig Brand discovered phosphorous. Copper has been used by humans for as much as 7000 years and elements such as gold, silver, tin, lead and mercury have been known for many thousands of years.
