Which type of bonding involves sharing of valence electrons between atoms?

Explanation:
Sharing valence electrons between atoms defines covalent bonding. In covalent bonds, atoms (usually nonmetals with similar electronegativities) meet their outer-shell needs by sharing electrons, forming bonds that can be single, double, or triple as in H2, O2, CO2, or CH4. This contrasts with ionic bonding, where electrons are transferred to create oppositely charged ions held together by electrostatic attraction; hydrogen bonding, which is a strong intermolecular force between molecules (not a true bond that shares electrons); and metallic bonding, where electrons are delocalized over a lattice of metal atoms. So, the type of bonding that involves sharing valence electrons is covalent bonding.
