Answer:
the valency is equal to eight minus the number of electrons in the outer shell.
Explanation:
In ionic compounds, valency gives an indication of the charge an ion formed from a particular element will carry. Take for example, magnesium, Mg, this has a valency of two and tends to form ions carrying two positive charges, Mg2+.
