Answer: Valency of Al in
Al_2O_3 is +3.

Step-by-step explanation:

The capacity of an element to gain or lose electrons is called valency of the atom or element.

The valency of oxygen is -2 is the compound
Al_2O_3 and let the valency of Al is x over here.

Therefore, valency of x will be calculated as follows.


2x + * 3(-2) = 0 (as the charge on compound is 0)


2x - 6 = 0


x = +3

Therefore, valency of Al in
Al_2O_3 is +3.
