Nickel mostly forms the +2 ions with several anions so its valency is +2. So the valency of nickel is 2
Calcium is a element. Nitrate is a ion. Calcium shows +2.
The oxidation number of nitrogen in the nitrate ion (NO3-) is +5. This is because oxygen generally has an oxidation number of -2, and the overall charge of the nitrate ion is -1. Thus, nitrogen must have an oxidation number of +5 to balance the charge.
The oxidation number of lead (Pb) in lead nitrate (Pb(NO3)2) is +2. In this compound, the nitrate ion (NO3-) carries a charge of -1, and there are two nitrate ions for every lead ion. The overall compound must be electrically neutral, making the oxidation number of lead in lead nitrate +2.
The most common oxidation number for nickel is +2. Nickel is a transition metal that can also exhibit oxidation states of +1, +3, and +4, but the +2 oxidation state is the most stable and commonly observed.
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 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 of chromium in CrNO3 is +3. This is because the overall charge of the nitrate ion (NO3-) is -1, and there are 3 nitrate ions in Cr(NO3)3. Therefore, the oxidation number of chromium must be +3 to balance out the -3 charge from the nitrate ions.
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 nitrogen in the nitrate ion NO3- is 5
In Ag NO3 the oxidation number of Ag (Silver) is 1+, the oxidation number of N (Nitrogen) is 5+, and the oxidation number of O (Oxygen) is 2-.
Nickel nitrate typically appears as a green crystalline solid.
NH₄NO₃ (ammonium nitrate), the oxidation number of nitrogen in the NH₄⁺ ion is -3, and in the NO₃⁻ ion is +5. The overall charges balance with the ammonium ion being +1 and the nitrate ion being -1.
