Assign oxidation numbers to each element in this compound. NO

+2, - 2

Explanation:

As per the rule of assigning oxidation number, the oxidation number of O atom is - 2. The sum of the oxidation number of a neutral compound is zero. Let us assume x to be the oxidation number of N.

x + (-2) = 0

x - 2 = 0

x = + 2

Therefore the oxidation of N in NO is + 2 and and the oxidation of O in NO is - 2 respectively.

NO - --> N + 2 and O - 2

Explanation:

Oxidation numbers are assigned to the elements of a compound to keep a track of the number of electrons each atom has.

Here we have a compound NO (Nitrogen Oxide). The Nitrogen is assigned an oxidation number of + 2 while Oxygen in this compound is assigned an oxidation number of - 2.

So the algebraic sum of the oxidation numbers of the elements in the compound NO is equal to zero.
