    because of where it is on the periodic table. It loses 4 electrons so it becomes 4+

    Sometimes charges can vary but one that is always pretty consistent is oxygen. Almost any time you have O in a compound such as SO2, the O will have a -2 charge.

    Since SO2 has to have a charge of zero (no charge is given so assume it is zero), the two Os in the molecule will add up to a -4 charge since each has a -2 charge (-2*2=-4). To balance this out, S must have a +4 charge (-4 + +4=0).
