Which transition metals form one kind of ion. Silver(Ag) 1+ and Zinc(Zn)2+.

The charges of the other transition elements can always be found in ionic compounds using the number of molecules of the other ion. For example, in #Fe_2 O_3# The charge of iron is 3+ because the charges of each ion in the ion must total in zero. Oxygen's charge is 2-, so the least common multiple is six, so (#3##xx2^-## = 6^-#).
And since (#2##xx3^+## = 6^+#), and (#6^+##xx6^-## = 0#), the charge is neutral(0). In this way the charge of individual elements in binary ionic compounds can be found by using the number of the other atom within the compound.
