Which of these is a typical property of a substance that is composed of atoms that are held together by covalent bonds? a. it conducts electricity when in solid form. b. it conducts electricity when in molten form. c. it conducts electricity when it is dissolved in water. d. it does not conduct electricity in any form.

D. It does not conduct electricity any form.

Explanation:

Covalent bond is formed by the sharing of electrons between two non-metal atoms. To conduct electricity there must be free flowing of electrons, which is not possible in molecules that are held together by covalent bonds as the electrons are shared and not readily available for free flow. However, metals conduct electricity as in a metallic bond the metal cation shares a network of free moving electrons.
