Question

Element oxygen is divalent

Give reason

if you don't now then don't ans the question​

Answer 1

Answer:

The atomic number of oxygen is 8. In it's outermost shell there are six electrons and it would be stable it needs eight electrons in its outermost shell for completing its octet. So it will form two bonds to complete its octet. Hence it is called divalent.

Answer 2

Answer:

hlooo....gud evngg..

Explanation:

i think,The atomic no of oxygen is 8,so there are 6 electrons,in its outermost shell....so to attain stability they need 8 electron into it's outermost shell..for completing it's octect..so it will form 2 bonds to complete it's octect...hence it is divalent..

hope it's helpful to u....

Thank u
