Question

what property do all of the group 18 elements have that makes them stand out from other elements?
they are the only nonmetals that are liquid at room temperature.
they are the only nonmetals that are solid at room temperature.
they are very likely to bond with any element, whether it is metallic or not.
they are very unlikely to bond with any element, whether it is metallic or not.

Explanation:

Group 18 elements are noble gases. They have a full valence shell of electrons, which makes them very stable. Due to this stability, they are very unlikely to bond with any other element (whether it is metallic or not) as they do not need to gain, lose, or share electrons to achieve a stable electron configuration.

Answer:

They are very unlikely to bond with any element, whether it is metallic or not.
