The nature of the hydrogen bond is studied in the context of the Spacetime Wave Theory. The usual description of a covalent bond is: a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons is known as covalent bonding [1]. This picture of the hydrogen bond is challenged by suggesting that rather than overlapping in the space between the nuclei, the electrons position themselves to occupy an approximately hemispherical region on the remote side of the nucleus from the other atom.
