Which statement explains why neon is a group 18 element?
(1) neon is a gas at stp.(2) neon has a low melting point.
(3) neon atoms have a stable valence electron configuration.
(4) neon atoms have two electrons in the first shell.

The answer is (3). Neon atoms have a stable valence electron configuration. This is a characteristic of Group 18 elements. This makes these elements not easy to react with other substances.
