Answer:

It is a noble gas.

Step-by-step explanation:

The element in question is helium, a noble gas. It has a full shell of eight valence electrons like all the other noble gases, which means that it does not have to react with other elements in order to obtain a full octet of valence electrons. This means that it does not react with other elements.
