WebMay 7, 2024 · The covalent bond involves the electrostatic interactions of valence electrons and multiple nuclei of the atoms that form the bond. There are both attractive forces between opposite charges, and repulsive forces between like charges, and these can be described by Coulomb's law: E = k q1q2 (4πϵ0)r F = k q1q2 (4πϵ0)r2. E is the bond energy.
