Cerium(III) is more stable
Yes, it is
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.
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
Oxidation state of O is -2.Oxidation state of S is +4.
It depends on what form it is in. It can be in the 4+ oxidation state, 4- oxidation state and every oxidation state in between.
+4 is the most common and the most stable oxidation number

Technetium can have oxidation states ranging from -3 to +7. However, the most common and stable oxidation state for technetium is +7.
Oxidation state of O is -2.Oxidation state of S is +4.
It depends on what form it is in. It can be in the 4+ oxidation state, 4- oxidation state and every oxidation state in between.
+4 is the most common and the most stable oxidation number
The oxidation state 4+ is not stable in PbCl4; the reaction is:Pb4+ + 2 e---------Pb2+
+4 oxidation state
+4 oxidation state
S = +4 oxidation state O = -2 oxidation state
