Question

The word family implies that the elements in a family have like properties. What property do the elements of the noble gas family all share?

Answer 1

They are not reactive.

Answer 2

They are chemically inert

Step-by-step explanation:

Noble gases as the name suggest are gases. So that is one of the similarities that they share. But their more important similar property is that they are chemically inert i.e they are unreactive. This is due ti the fact that they have full outer energy levels which is why they never take part in chemical reactions because their electronic structure is already stable.
