electrovalent bond
  • noun a chemical bond created by the transfer of electrons from one atom to another giving a structure in which oppositely charged ions are held together by attraction forces
  • A chemical bond formed by the electrostatic attraction of the oppositely-charged ions which form the resulting compound. In such a bond, each constituent either gains or loses one or more electrons. For instance, in NaCl (table salt), the sodium transfers one electron to the chlorine. In the process, the sodium becomes a positively-charged ion, and the chlorine a negatively-charged one. Also called ionic bond.
