Magnesium nitride (Mg3N2) is formed by the reaction of magnesium metal (Mg) with nitrogen gas (N2). Let x be the oxidation number of Mg in Mg3N2 .Since the overall charge on the compound is 0 , the sum of oxidation states of all elements in it should be equal to 0 .Therefore, 3x + 2( - 3) = 0 or, x = + 2 Hence, the oxidation number of Mg in Mg 3N2 is + 2 . Directions: In the following questions, give the oxidation number of the indicated atoms/ion. Thus it is reduced, while Mg is reducing agent and it is oxidised because the oxidation number of Mg increases (0 to +2) while that of N decreases (0 to -3). Assign Oxidation Numbers and write separate equations for each half reaction, then work on each half– reaction separately. 2.
