Explain all the Rules to assign oxidation number.
Answers
Answer:
(1) All atoms in the elemental or molecular state have 'zero'oxidation state.
(2)Elements of group I and II in the periodic table always have
′
+1
′
and
′
+2
′
oxidation states respectively.
(3). Hydrogen
′
+1
′
oxidation state in all its compounds expect metal hydrides where it is
′
−1
′
(4) Oxygen has been assigned an oxidation number of
′
−2
′
in all its compounds except peroxides and oxygen fluoride. In peroxide it is
′
−1
′
and in oxygen fluoride it is
′
+2
′
.
(5) Halogens generally have
′
−1
′
oxidation state. Except for fluorine, other halogens may have positive oxidation states in their oxides and inter halogen compounds (Flurione always has
′
−1
′
state).
(6) The algebraic sum of oxidation numbers of all the elements in a compound is zero and that in ion is equal to the net charge on the ion.
