A lot can be determined from which column the element is in on the periodic table. Going across the second row the charges are 1+ 2+ 3+ 4+ 3- 2- 1- 0 All the elements in those columns will have those charges. Most the the transition metal columns have multiple charges. Col 3 (Sc) is 3+. Col 12 (Zn) is 2+ Other than that, just memorize some of the most common metals Pb, Pt, Pd, Sn are 2+, 4+ Fe, Ni, Co, are 2+, 3+ Cu 1+, 2+ Ag 1+ only Au 1+, 3+
