The element represented here is Aluminium.
Valency of Aluminium = 3

I HOPE IT HELPS U

sandhys1: i know valency of an elements doesn't involve a positive or negative sign but the optins are +3 or -3 ...so can u pls tell is it +3 or -3?

arjunchhimpa: right

arjunchhimpa: bcz F have np5 configuration in his outermost shell. and F wanna get one electron to get full complement configuration

Answered by arjunchhimpa

Correct answer is C(+3).
This electron configuration of Al.
For Al more stable oxidation state is +3 as comparison to - 2.because when Al looses 3 electrons then Al gets full complement configuration. As we know that full complement configuration more stable than another. So most probable valency is +3.
I hope it may help u
Regards
