Assertion : The oxidation numbers are artificial, they are useful as a book keeping device of elements in reactions
Reason : The oxidation numbers do not usually represent real charge on atoms, they are simply conventions that indicate what the maximum charge could possibly be on an atom in a molecule.

Assertion: In azide ion average oxidation number of N is -1//3 . Reason: In azide ion two N atoms have zero oxidation number and one has oxidation number -1 .

Oxidation number is the charge assigned to an atom of a molecule or ion according to some arbitry rules .In neutral molecules , the sum of the oxidation numbers of all the atoms present is zero while in a simple or complex ion it is equal to the net charge on ion. In some cases the oxidation number may be even fractional. Athough sometimes a particular elemenet may have same valency and oxidation state but these are based upon different concepts.The number of oxidation states available for a particular elements are normally more than the valencies A brown complex has the formula: [Fe(H_(2))(O)_(5)NO]SO_(4) the oxidation number of iron is:

Assertion :- In NH_(4)NO_(3) , the oxidation number of the two N-atoms is not equal. Reason :- One N atom is present in the ammonium ion while the other is present in the nitrate ion.

The ion of an element has 3 positive charges. The mass number of atom of this element is 27 and the neutrons is 14. What is the number of electrons in the ion ?
