The most common oxidation state for nickel is +2. Nickel can also exhibit oxidation states of +1, +3, +4, and +0 in certain compounds.
The most common oxidation number is +II. The charge and number for cobalt is +2.
To find the oxidation number for Ni (nickel), you look at the overall charge of the compound or ion it is a part of. For example, in NiCl2, each Cl has an oxidation number of -1, so the sum of the oxidation numbers must equal the overall charge of the compound. Therefore, as NiCl2 is neutral, the oxidation number of Ni must be +2.
The oxidation number of nickel (Ni) in NiO2 is +4. Oxygen typically has an oxidation number of -2, so the total oxidation number of the compound is 0. Since there are two oxygen atoms in NiO2, the oxidation number of nickel must be +4 to balance out the charge.
The oxidation number for Ni in NiS (nickel sulfide) is +2, while the oxidation number for S (sulfur) is -2. This is because in a compound, the overall charge must be neutral.

The oxidation number for Ni in NiO2 is +4. Nickel is known to have variable oxidation states, and in this compound, it is bonded to two oxygen atoms which have an oxidation number of -2 each. The overall charge of the compound is neutral.
The oxidation number of Ni in Ni(OH)2- is +2. This is because each hydroxide ion has a charge of -1, and the overall charge of the compound is -1. Therefore, the nickel ion must have a charge of +2 to balance the charge of the two hydroxide ions.
The oxidation number of nickel in nickel nitrate is +2. In nickel nitrate, the nitrate ion has a charge of -1, and since the overall compound is neutral, the nickel ion must have an oxidation state of +2 to balance the charges.
It is equal to the charge. Oxidation number depends on charge.
The oxidation number of hydrogen (H) is always +1. Since the overall charge of H2Co is 0, the oxidation number of carbon (C) would be +2, based on its common oxidation state in compounds.
The common oxidation number means any number that indicates the charge of atoms when an electron is either lost, gained, or shared in a chemical bond. It is known as the ion's number. Also, oxidation numbers in all atoms in a compound must add up to zero.
The oxidation number for CO3 with a charge of -2 is 2.
