Four covalent bond s. Carbon has four valence electrons and here a Valence ( chemistry ) | valence of four.

Valence electrons are their " own " electrons, present in the free neutral atom, that combine with valence electrons of other atoms to form chemical bonds.

Valence electrons can determine the element's chemical properties and if it will bond with others or not.

Valence electrons are important in determining how the atom reacts chemically with other atoms.

Valence electrons have the ability, like electrons in inner shells, to absorb or release energy in the form of photons.
