###### Problem Details

Give the oxidation state for the metal ion in each of the following compounds, respectively:

K2O, CaO, TiO2 , V2O5

Enter the oxidation states of the metals in the order given, separated by commas (e.g., +1,+3,-2,+2)

Metals often react with oxygen to produce ionic oxides such as K2O, CaO, TiO2,and V2O5
