On the periodic table, argon belongs to group 18, which is the noble gas group or family. Argon is an inert gas that has the atomic number of 18 and a melting point of -308.83 degrees Fahrenheit. Its chemical symbol is Ar.
Sir William Ramsay and Lord Rayleigh were the two chemists who discovered this element in 1894. Argon, which is a colorless and odorless gas, is present in small amounts in the atmosphere. Through the process of fractional distillation, Ramsay and Rayleigh isolated argon from liquid air.
Because argon is inert, it's used as an inert gas shield for welding, as well as in incandescent light bulbs, lasers and glow tubes. Argon lasers and argon-dye lasers are important in the medical field for use in eye surgeries and for the treatment of certain skin conditions.Learn More

The element scandium is in the third family of the periodic table. Each column of the table is called a group or family, and from left to right, they are numbered one through 18. Scandium is in the third column, so it is in group three.Full Answer >
Although hydrogen is normally listed at the top of Group I, the alkaline metals, on the periodic table, there is much debate as to which group it should belong. Many chemists believe hydrogen doesn't belong in any group and that Group I begins with lithium.Full Answer >
Zirconium belongs to group 4 on the periodic table, which is part of the larger family known as the transition metals. According to the Jefferson Lab website, other elements in group 4 are titanium, hafnium and rutherfordium. Zirconium, titanium, hafnium can be found in nature, while rutherfordium only exists in the laboratory.Full Answer >
