Krypton is in Group 8 of the Periodic Table, along with other Noble Gases such as Helium and Neon. Group 8 are known as the Noble Gases as they have a full outer shell of electrons, and don't need to bond to other atoms to full up their electrons, so they exist as single gaseous atoms.

So, how many atoms are there in a Krypton molecule? One (it's technically not a molecule, but an atom, you don't get Krypton molecules!)
