Valence electrons
Explanation:
In an atom, the valence electrons are the sub-atomic particles most directly involved in chemical bonding.
Valence electrons are the electrons in the outer most shell of an atom that are involved in chemical reactions.
Atoms of some elements show no tendency to combine with themselves or other kinds of atoms because their outer energy levels are completely filled.
The driving force for many interatomic bonding is the tendency to have completely filled outer energy levels.
To complete an atomic configuration, electrons are either gained or lost from the outermost shell where the valence electrons reside.
