Cerium(III) is more stable
The Cerium ion can hold a charge of +2, +3 and +4. The +2 state is rare can only seen with elements H2, I2, and S. Often seen in the form of Cerium(IV) oxide.
0 in the elemental form, +3 and +4 are more common in its compounds.
Manganese has oxidation states from +7 to -3. In elemental state it is oxidation state 0.
Manganese(VII) chloride (MnCl7) does not exist as a stable compound due to high oxidation state and lack of suitable ligands to stabilize it. Manganese commonly forms stable compounds up to an oxidation state of +4.
Oxidation state of O is -2.Oxidation state of S is +4.

Manganese has oxidation states from +7 to -3. In elemental state it is oxidation state 0.
Manganese(VII) chloride (MnCl7) does not exist as a stable compound due to high oxidation state and lack of suitable ligands to stabilize it. Manganese commonly forms stable compounds up to an oxidation state of +4.
Technetium oxidation states are between -1 and +7; the most usual valences are +3, +4 and +7.
Oxidation state of O is -2.Oxidation state of S is +4.
+4 is the most common and the most stable oxidation number
Here O S of C is -4As,let us take O S of C as xSo, O S of H is +1In CH4 as it is stable so the eq. isx+4(+1)=0or, x = - 4
The oxidation state of carbon (C) in CO2 is +4. Each oxygen atom in CO2 has an oxidation state of -2, so for the overall molecule to be neutral, carbon must have an oxidation state of +4.
