Describe what a hydrogen bond is
WebJul 15, 2024 · The two electrons (one from each hydrogen atom) “belong” to both atoms. Each hydrogen atom feels the effect of the two electrons; each has, in a way, filled its valence energy level. A covalent bond is formed. The overlapping of the electron orbitals and the sharing of an electron pair is represented in part (a) of the following figure. WebMar 2, 2024 · hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces.
