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.

Answer 1

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

The group 18 elements are placed in the far right side of the period table. The group contains noble gases which are; argon, helium, xenon, neon, krypton, and radon. The noble gases are unreactive because they have complete octets (valence shell). They are unlikely to bond with any element to form compounds. The noble gases have weak interatomic forces, and high ionization energies which reveal their chemical inertness.
