Wrong question. Valency and valence electrons are two things. We've all been taught this and I wonder why some students here are speaking ignorantly, as if they have never been to a science class!.
Back to the question above, the Valence electron is 5 and it's valency is 3. Thanks.

What the question means is the total number of valence electrons contained,which is 2,the valence electrons are 3 and 5
