WebThe bond length is the internuclear distance of two covalently bonded atoms. It is the distance from the nucleus of one atom to another atom which forms the covalent bond. The greater the forces of attraction between electrons and nuclei, the more the atoms are pulled closer to each other. This decreases the bond length of a molecule and ... WebCovalent bonds meanwhile usually occur between non-metals. As long as the individual atoms can form an octet of electrons from sharing electrons in a covalent bond, there's always a possibility. So nitrogen for example is a non-metal with 5 valence electrons and needs 3 more for an octet, and can form a variety of covalent bonds.
