2+
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.
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.
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 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.
It is equal to the charge. Oxidation number depends on charge.
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.
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 oxidation number for CO3 with a charge of -2 is 2.
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.
