A sixth position can reversibly bind oxygen by a coordinate covalent bond, completing the octahedral group of six ligands. Such association through sharing of electron pairs among different or same kinds is known as Covalent Bond. So, if two identical nonmetals (e.g., two hydrogen atoms) bond together, they will form a pure covalent bond. The simplest interpretation of the decrease in energy that occurs when electrons are shared is that both electrons lie between two attracting centres (the nuclei of the two atoms linked by the bond) and hence lie lower in energy than when they experience the attraction of a single centre.
