Examples :
CaCl2. Formation of Ca2+(Cl−)2. Electrovalency of Calcium is +2 and is called positive electrovalency. Electrovalency of Chlorine is −1 and is called negative electrovalency.
Explanation:
I am confused with the example but the meaning is correct... I hope it's helpful for you...
The valence is known as an element's combining power. Some elements vary in their ability to interact with other elements, depending on the nature of the reaction; variable valence is called this property. Iron (Fe), for example, may have a valence of both 2 and 3.
