electrovalencyn.

1923 Jrnl. Chem. Soc. 123 822 Whilst a single bond may be either a covalency or an electrovalency, a double bond in organic chemistry usually reacts as if it contained one covalency and one electrovalency.

1954 A. J. Berry From Classical to Mod. Chem. viii. 200 Langmuir..emphasized the fundamental distinction between electrovalency in which the union is effected by a transference of electrons, and covalency in which the electrons are shared.

1958 E. S. Gilreath Fund. Concepts Inorg. Chem. vi. 275 In a crystal produced by the deposition of ions there frequently appears a tendency for the electrovalencies of the constituent particles to acquire a covalent character.

1999 Cement & Concrete Res. 29 1550/1 On the one hand, the lattice would be distorted by the unequal bond force and ionic size; on the other hand, lattice defects would be created for maintaining electrovalency equilibrium.
