When an atom or molecule gains one or more electrons, it is said to beA. reducedB. polarizedC. oxidizedD. energized
MArishka [77]
Ƒ An atom that gains one or more electronswill have a NEGATIVE charge. ƒ An atom that loses one or more electrons will have a POSTIVE charge. ƒ An atom that gains or losesone or more electrons is called an ION. ƒ A positive ion is called a CATION and a negative ion is called an ANION.

From this information above you can see its negative so it means it gets reduced
hope it helped

In this reaction the lead atoms gain anelectron (reduction) while the oxygen loses electrons (oxidation). Magnesium loses electrons and is therefore said to be "oxidized", whereas the chlorines gain electrons and are said to be reduced
and as you can see oxidation only happens when oxygen is reduced
