The element Argon has 8 Isotopes argon-35, argon-36, argon-37, argon-38, argon-39, argon-40, argon-41 and argon-42.The stable isotopes of argon are:argon-36, 0.34%argon-38, 0.06%argon-40, 99.60%Of the radioactive isotopes argon-39 has the longest halflife at about 260 years, all the others have halflives measured in days or much less.
Argon is an element and all the atoms in argon are argon atoms.

Hardness is measured in three types viz., Moh's hardness, Brinnel hardness and Vicker' hardness. Hardness of Iron is, 1) Moh's Hardness-4, 2) Brinnel Hardness-490 Mpa, 3) Vicker's Hardness-608 Mpa
Curiously enough, the name of argon Is argon.
Argon is used to make argon
