Oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.. Each atom that participates in an oxidation-reduction reaction is assigned an oxidation number that reflects its ability to acquire, donate, or share electrons. B.

Try it risk-free for 30 days Try it risk-free Ask a question. Radon occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead. The two oxygen atoms, being much more electronegative than the metals take these four electrons and thus have an oxidation state of $-2$ each. and Gay-Lussac, L.-J.
