Question

The valenty of oxygen is 2. give reason​

Answer 1

Answer:

✧ Oxygen is a chemical element with symbol O and atomic number 8. Electronic configuration of oxygen is :

$(he)2 {s}^{2} 2 {p}^{4}$

i. e. 2,8,6. To complete the octet it require 2 more electrons, hence the combining capacity or valancy of oxygen is 2.

hope this much helps uh ❣️

Answer 2

Answer:

there is Need to be almost two electrons are present in the first shell there are 8 electrons are needed to from stable octate but oxygen only six electron and 2nd shell so oxygen 2 electron completely its octate

hence the valency of Oxygen is 2.
