Answer 2

Oxidation Number

a number appointed to a component in synthetic mix which speaks to the quantity of electrons lost (or picked up, if the number is negative), by a molecule of that component in the compound.  

Guidelines for Assigning Oxidation Numbers to Elements  

Guideline 1: The oxidation number of a component in its free (uncombined) state is zero — for instance, Al(s) or Zn(s). ...  

Standard 2: The oxidation number of a monatomic (one-particle) particle is equivalent to the charge on the particle, for instance:  

Standard 3: The aggregate of all oxidation numbers in a nonpartisan compound is zero.

oxidation number of U in Uo2 (No3)2 is 2
