Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type...
This means that delocalization (electron sharing), as used in the Hellmann–Ruedenberg [40,49,50,51,52,53,54,55,56,57,58,59,83] energy analysis of covalent bonding, is a dynamical process. The shared electron, in addition to moving in the proximity of one nucleus, will transfer to the other nucleus and back with a well-defined periodicity.

Four electrons can be shared, for example, two coming from each participating atom; such a bond is called a double bond. Double bonds are shorter and stronger than single bonds and have a characteristic effect on the three-dimensional geometry of molecules containing them.
Electron sharing between an atom of carbon and four atoms of hydrogen meets the requirements of all atoms. The bonds are covalent because the electrons are shared. Although hydrogen often participates in ionic bonds, carbon does not because it is highly unlikely to donate or accept four electrons.
