Solution
neon
Explanation -
Carbon shares its valence electrons with other atoms of carbon or with atoms of other elements. The shared electrons belong to the outermost shells of both the atoms and lead to both atoms attaining the noble gas configuration. After sharing four electrons with four univalent atoms, carbon attains the electronic configuration of the noble gas Neon (2,8).
