How many valence electrons does Al -3 have?

Answer 1

Al -3 gains 3 electrons so Al has 13 electrons..the configuration is: 1s^2 2s^2 2p^6 3s^2 3p^1

Answer 2

Aluminum typically has 3 valence electrons in its neutral state. Since the charge of Al is -3 in this case, it has gained 3 electrons. Therefore, Al -3 has 6 valence electrons.
