In any period, the valency of an element with respect to oxygen

Question

In any period, the valency of an element with respect to oxygen (A) increases one by one from IA to VILA (B) decreases one by one from IA to VIIA (C) increases one by one from IA to IVA and then decreases from VA to VIIA one by one (D) decreases one by one from IA to IVA and then increases from VA to VIIA one by one.

As we move along the period, an electron is subsequently added in the outer most shell of the elements and valency increases. However when the number of valence electrons is more than

4,

then the valency is given by

valency

= 8 -

valence electrons

Q. In any period, the valency of an element with respect to oxygen

increases one by one from $I A$ to $V I L A$

decreases one by one from $I A$ to $V II A$

increases one by one from $I A$ to $I V A$ and then decreases from $V A$ to $V II A$ one by one

decreases one by one from $I A$ to $I V A$ and then increases from $V A$ to $V II A$ one by one.

As we move along the period, an electron is subsequently added in the outer most shell of the elements and valency increases. However when the number of valence electrons is more than $4,$ then the valency is given by

valency $= 8 -$ valence electrons
