hint:
valence electrons determine the chemical behaviour of an element, and they belong to the most external shell of an atom

D

abmon98 · Answer

The valence electrons(outer electrons) of an atom, which are involved in chemical bonding. Valence electrons account for similarities in chemical behaviour among elements within each of the groups. as @Michele_Laino has mentioned. Noble gases such as neon, argon, xenon and krypton are highly unreactive because their outermost shells holds 8 electrons.

abmon98 · Answer

when atoms interact to form a chemical bond, only their outermost shell which what holds the valence electrons are in contact.
