WebCovalent compounds are generally poor conductors of electricity: During the formation of a covalent bond, when the electrons get shared within the bonds, hence, there are no electrons or ions available to conduct electricity. As we know the electrons or ions are responsible for the electrical conductance of a substance. 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 …
WebJul 7, 2024 · 1.What are nonpolar covalent bonds? Nonpolar covalent bonds are generally formed whenever there seems to be an equal share of electrons among the atoms.
