what elements can h-bond
A hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom, covalently bound to a highly electronegative atom such as nitrogen, oxygen, or fluorine, experiences the electrostatic field of another highly electronegative atom nearby. Hydrogen bonds can occur between molecules or within different parts of a single molecule. Depending on the nature of the donor and acceptor atoms which constitute the bond, their geometry, and environment, the energy of a
