Question

If an atom loses electrons its oxidation state changes from

  1. Positive to negative
  2. Zero to negative
  3. Positive to zero
  4. Zero to positive

hintHint:

If an atom loses electrons, its oxidation number will increase.

The correct answer is: Zero to negative


    Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. 
    If an atom loses electrons, its oxidation number will increase. So, we can say it can be from zero to positive.
