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 two atoms and a force that holds them together. There is an attractive force between positively and negatively charged particles that is called the electrostatic force. The positive protons in the nucleus of one atom are attracted to the negative electrons of another atom.
