Neon
Noble gases' atoms have the least tendency to form ions.
It's a noble gas with a full outer shell of valence electron. It is naturally averse to losing any of them.
argon because it is a noble gas and noble gasses are the least reactive of all groups. sincerely a 13 year old.

helium
Noble gasses are least reactive of all the elements. So the least reactive element in the period 4 is Krypton. It is a noble gas with an atomic number of 36.

argon because it is a noble gas and noble gasses are the least reactive of all groups. sincerely a 13 year old.
Argon is the least likely in the list to react with other elements, because argon is a noble gas and none of the other elements in the list is.
Noble gases are least reactive because they have a full shell
xenon
Helium, the noble gas with the smallest atoms.
The gas most likely is one of the noble gases.
Krypton (Kr)
