Question

Oxidation number of an element in elemental form is
(a) negative
(b) positive
(c) zero
(d) +1​

Answer 1

Answer:

negative is the answer..

Answer 2

Answer:

(C) Zero (0) is the correct answer

Explanation:

The oxidation number for an element in its elemental form is 0 (holds true for isolated atoms and elemental substances which bond identical atoms: e.g. Cl2, etc) The oxidation number of a monoatomic ion is the same as its charge (e.g. oxidation number of Na+ = +1, and that of S2- is -2)
