oxygen is divalent because its valency is 2
nitrogen is trivalent because its valency is 3

Hi there!

The atomic number of oxygen is 8.
It's electronic configuration would be : 2, 6
Now in its outermost shell there are six electrons and it would be stable it needs 8 electrons in its outermost shell...for completing it's octet.
So it will form 2 bonds to complete it's octet...and hence it is called diavalent.



The atomic number of nitrogen is 7.
It's electronic configuration would be : 2, 5
Now in its outermost shell there are five electrons and it would be stable it needs 8 electrons in its outermost shell...for completing it's octet.
So it will form 3 bonds to complete it's octet...and hence it is called trivalent.

HOPE HELPS!
