argon is a noble gas, number 18 with a mass of about 40 amu. noble gases almost never make compounds, so it's chemical property is that it is almost totally unreactive with other elements. Physically it is a gas until just about minus 200 centigrade, when it can liquify. gases have very low density. there's not much going on with noble gases, they're called noble as an insult to the nobility of the European aristocracy. The nobles never mingled with the peasants, and isolated themselves from the rest of society. Noble gases never "mingle" with peasant elements either.
