What are the oxidation numbers of the metal ions in: #Mo_3(PO_4), Mo^(+I); Mn_2O_3, Mn^(III+); CrO, Cr^(+II); CuSO_4, Cu^(+II);TiBr_3, Ti^(+III); YF_4?#

#Ag^(+I)#..........

Explanation:

The oxidation number is the charge left on the central atom when all the bonding pairs of electrons are REMOVED, with the charge assigned to the most electronegative atom.

#Mo_3(PO_4), Mo^(+I); Mn_2O_3, Mn^(III+); CrO, Cr^(+II); CuSO_4, Cu^(+II);TiBr_3, Ti^(+III); YF_4?#.

#YF_4# is unknown; you mean #YF_3rarrY^(+III) + 3F^-#.
