The polar covalent bonds that form between hydrogen atoms and other atoms can give rise to a third type of chemical bond, a hydrogen bond (Figure 2.6) It forms when a hydrogen atom with a partial positive charge (δ+) attracts the partial negative charge (δ−) of neighboring electronegative atoms, most often larger oxygen or nitrogen atoms.

· 3.2: Chemical Bonds. Chemical bonds form when electrons can be simultaneously close to two or more nuclei, but beyond this, there is no simple, easily understood theory that would not only explain why atoms bind together to form molecules, but would also predict the three-dimensional structures of the resulting compounds as …
There are three main types of chemical bond: Covalent bond . It occurs when non-metallic atoms of similar (usually high) electronegativities come together to share electrons from their last orbit to form a stable chemical compound. Ionic bond . It consists of the union of metallic and non-metallic atoms, through a transfer of electrons from the ...
