Answer: The oxidation state of a free element (uncombined element) is zero. For a simple (monoatomic) ion, the oxidation state is equal to the net charge on the ion. For example, Cl– has an oxidation state of -1. When present in most compounds, hydrogen has an oxidation state of +1 and oxygen an oxidation state of −2.
hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D Explanation:

Sodium oxide + Water= Sodium hydroxide
Non metals are electronegative in nature whereas metals are electropositive. A non-metal accepts electron and gains negative charge whereas metals lose eletrons and gains positive charge. Hence correct answer is non-metals. Hope this helps!
