1. Electrovalency
In the formation of an electrovalent compound (or ionic compound),the number of electrons lost or gained by one atom of an element to achieve the nearest inert gas electron configuration is known as its electrovalency.The elements which lose electrons form positive ions, so they have positive electrovalency.The elements which gain electrons form negative ions, so they have negative electrovalency.The following examples will make it more clear.
