Group 8A – The Noble or Inert Gases. Group 8A (or VIIIA) from the periodic table would be the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
Argon is really a chemical element with symbol Ar and atomic number 18. Considered a noble gas, Argon is really a gas at 70 degrees.

What are the 18 groups in periodic table?
Groups are numbered 1–18 from left to right. The weather in group 1 are classified as the alkali metals individuals in group 2 would be the alkaline earth metals individuals in 15 would be the pnictogens individuals in 16 would be the chalcogens individuals in 17 would be the halogens and individuals in 18 would be the noble gases.
Is argon a molecule or atom?
The element argon happens to be a loner. It’s among the inert gases that normally exist as single atoms. However in the 23 August issue of Nature, chemists are convinced that they convinced argon to mingle just a little and form a substance along with other elements.
