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 chemical bond is an attraction between atoms. This attraction may be seen as the result of different behaviors of the outermost or valence electrons of atoms. These behaviors merge into each other seamlessly in various circumstances, so that there is no clear line to be drawn between them.
