Neon
Helium and Neon - neither react in their own right so with each other is impossible.
Helium, neon and argon are the least likely elements to form compounds.
oxigen
argon because it is a noble gas and noble gasses are the least reactive of all groups. sincerely a 13 year old.
Neon
Nobel gasses.
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.
These are the so-called noble gases.
Argon is chemically inert due to the presence of completely filled orbitals. So it is does not react with other elements at STP.
Group-18 elements least react with other elements. They are inert in nature. They are called noble gases.Elements in group 18 are less likely to react with any other elements. This group is made out of the noble gases. Its members are He, Ne, Ar, Kr, Xe and Rn.
Helium and Neon - neither react in their own right so with each other is impossible.
Family background
The boron family does not react to many items. However, the one group that it does react violently with is the halogen group.
noble gases, or inert gases they are the same thing and they are group 18 they have full valence electrons so they are unlikely to react with other elements
Keep your own dignity and don't stoop to their level. If you respect them, they are more likely to respect you.
Is what as least as likely as not? that is myquestion to you!
