Question

Fill in the blank spaces in the following statements.
1. The valency of aluminium in aluminium oxide is...........​

Answer 1

Explanation:

The charge of Aluminium is +3 and the charge of Oxygen is -2. Therefore, we can conclude that the valency of Aluminium in Al2O3 is 3 and the valency of Oxygen in Al2O3 is 2. Note: Aluminium loses the 3 valence electrons to gain the noble gas configuration of Neon, which is 2,8.

Answer 2

Answer:

aluminium valency = 3 and oxygen valency = 2
