WebNov 4, 2024 · You may assume that the valences of the elements—the number of electrons with which an atom will bond or form—are those that can be derived by looking at the groups (columns) of the periodic table. While these are the most common valences, the real behavior of electrons is less simple. WebElectrovalency –The number of electrons lost or gained by an element to acquire the nearest inert gas configuration i.e. stable configuration is called electrovalency of that atom. For example, atoms of Li, Na, K lose one electron so their electrovalency is 1, atoms of Mg, Ca, Ba lose two electrons , so their electrovalency is 2.
