Explanation:
To solve this problem, we need to set up an algebraic equation. Let us first understand the meaning of oxidation number. 
The oxidation number is the formal charge assigned to an atom present in a molecule or formula unit
The algebraic sum of all oxidation numbers of atoms in an ion containing more than one kind of atom is the charge on the ion. 
The algebraic sum of all oxidation number of atoms in a neutral compound is zero;
    The radical NO₃ has a formal charge of -1; 
  let the oxidation number of Li = x 
  x + (-1) = 0 
   x = + 1
