electrovalency , auch: electrovalence

The electrovalency of an element or compound is expressed as a charge.

Electrovalency is used to help balance equations describing chemical reactions.

When an atom or molecule has an electrovalency of zero, it has no net electric charge.

Atoms or molecules that have lost electrons have an electrovalency greater than zero and are known as cations.

Electrovalency is a measurement of the net electric charge of an ion and is used when balancing chemical reactions.

When writing about an ion, the convention is to write the chemical formula followed by the electrovalency as a superscript, illustrated below:

One can see that the one positively charged hydronium molecule and one negatively charged hydroxide molecule have formed water which has an electrovalency of zero.

Electrovalency is related to the concepts of electronegativity and valence electrons, and indicates the number of electrons necessary for an ion to have a balanced electric charge.

Electrovalency is the type of chemical bonding, that is established by the actual transference of one or more valence electrons, from a metallic atom to a non-metallic atom, so that each of the 2 elements can attain the stable electronic configuration of their respective nearest inert elements in the periodic table.
