What is the oxidation number for calcium and nitrate?

Calcium is a element. Nitrate is a ion. Calcium shows +2.


Oxidation number of nitrogen in the nitrate ion?

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.


What is the oxidation number of lead in Lead nitrate?

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.


What is the most common oxidation number for nickel charge and number?

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.


What is the oxidation number for nickel?

The most common oxidation state for nickel is +2. Nickel can also exhibit oxidation states of +1, +3, +4, and +0 in certain compounds.


What is the oxidation number of NiO2?

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.


What is the oxidation number of chromium in CrNO3?

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.


How you can find the oxidation number for Ni?

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.
