Explain how valence electrons in an atom are used to form a full outermost energy level?

Atoms form chemical bonds to achieve a full outermost energy level by sharing, gaining, or losing electrons. Valence electrons are the electrons in the outermost energy level of an atom, and having a full outermost energy level makes the atom more stable. This stability is achieved when there are eight electrons in the outermost energy level, known as the octet rule.
