In an oxidation-reduction, or redox, reaction, one atom or compound will steal electrons from another atom or compound.Redox Reactions and Molecular Compounds. The loss or gain of electrons is easy to see in a reaction in which ions are formed. However, in many reactions, electrons are not transferred completely. Recall that in a molecular compound, electrons are shared between atoms in a type of bond called a covalent bond.An electric current is carried by the movement of either electrons or ions. In covalent substances the electrons are localized either as shared pairs or as lone pairs, and no ions are present. Since there are no charged particles free to move, covalent substances are poor electrical conductors.
