Cobalt is a transition metal. Its oxidation states are 2 (3).
Yes, It can exist in both a 2+ and a 3+ oxidation state.
Cr is a transition metal and has a variation of oxidation number from 0 in the elemental state to +6 in the dichromate ion.
The subscript of the second ion identifies the oxidation state of the transition metal
The oxidation number of what in K3PO4? In that compound the oxidation number of oxygen is -2, the oxidation number of potassium is +1, and the oxidation number of phosphorus is +5.Realistically, in most compounds you can generally take it as a given that the oxidation number of oxygen is -2 and the oxidation number of any alkali metal is +1. In potassium phosphate, that only leaves the oxidation number of phosphorus to figure out, and since they have to come out to a total of zero ...The oxidation number of a compound is essentially a meaningless phrase.

rust
Mg
The Roman numeral in the parentheses is the valence or oxidation of the metal that it follows. Transition elements have more than one oxidation number
Dubnium (Db)- It is a transition metal (5 oxidation states)
