The oxidation number of Al is +3 in the complex ion Al(OH)4-. Each hydroxide ion (OH-) carries a charge of -1, so the total charge of the complex ion is -1. Since there are four hydroxide ions, the aluminum ion must have an oxidation number of +3 to balance the charges.
The oxidation number of carbon (C) in Al4C3 is -4. This is because aluminum (Al) has an oxidation number of +3 and there are 4 aluminum atoms for a total oxidation number of +12. This must be balanced by the oxidation numbers of the carbon atoms, which must be -4 in order for the compound to be neutral.
The oxidation numbers in PO43- , phosphorus oxidation number=+5; oxygen = -2
Carbon is a pblock element. It shows -4 to +4 oxidation numbers.
It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
0 in the elemental form, +2 and +4 in its compounds

It depends on the compound. Lead can have an oxidation state of either 2+ or 4+
Carbon shows many numbers. the range is between -4 to=4.
The oxidation number is 0 in elemental form. It can have other oxidation numbers as -2, +4 and +6 in its compounds such as H2S, SO2 and SO3 respectively.-2, 0, 2, 4 and 6 oxidation states
The oxidation number of carbon in Na2CO3 is +4. This is because the oxidation numbers of sodium and oxygen are always +1 and -2, respectively, and the sum of the oxidation numbers in a compound must equal zero.
In SO2, the oxidation number for sulfur is +4 and for each oxygen is -2. The sum of the oxidation numbers of all atoms in SO2 will be zero since it is a neutral molecule.
4. They are +1, +2, +3, +4. The +1 and +2 oxidation numbers are the best known.
Berkelium has the valences 3+ and 4+.
