electrostatic bond, electrovalent bond, ionic bond - a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion. metallic bond - a chemical bond in which electrons are shared over many nuclei and electronic conduction occurs. peptide bond, peptide linkage - the primary linkage of all protein structures; the chemical bond between the carboxyl groups and amino groups that unites a peptide.
A double bond in chemistry is a chemical bond between two chemical elements involving four bonding electrons instead of the usual two. The most common double bond, that is between two carbon atoms, can be found in alkenes. Many types of double bonds exist between two different elements. For example, in a carbonyl group with a carbon atom and an oxygen atom. Other common double bonds are found in azo compounds (N=N), imines (C=N) and sulfoxides (S=O).
