Answer: Oxygen has six valence electron in its valence shell.
Explanation:
Valence shell : Outermost shell of an atom containing the valence electrons.
Valence electrons: Electrons in the outermost shell is known as valence electrons.
Oxygen has atomic number of 8.
\([O]=1s^22s^22p^4\)
From the electronic configuration of the oxygen we can see that there are six valence electrons present in its valence shell.
