Answer to Question #165260 in Inorganic Chemistry for Ray

Question

If A is true, write A. if B is true, write B. If both statements are true, write C. If both are false, write D. 

A. Oxidation number is the same as the atomic charge l for ionic compounds. B. For example, both Na and Cl has an oxidation number of 1.

Answer 1

Answer: C

The oxidation number of an atom is the charge that atom would have if the compound was composed of ions.The oxidation number of an atom is zero in a neutral substance that contains atoms of only one element. The oxidation number of simple ions is equal to the charge on the ion.

For example;

2 Na + Cl₂ → 2 NaCl

Consider the reactants. Because both reactants are the elemental forms of their atoms, the Na and Cl atoms as reactants have oxidation numbers of 0. In the ionic product, the sodium ions have an oxidation number of +1, while the chloride ions have an oxidation number of −1:
