Yes nickel is a cation. the formula for Nickel would be Ni+ for Nickel II it would be Ni+2 and for Nickel III it would be Ni+3
The answer is Ni3+
A positive charge is a positive electrical charge. Particles with no charge are called neutral particles.
Negative charge = electron Positive charge = positron Positive charge = proton
The charge of a nucleus is positive, as it contains protons which have a positive charge. The charge of an atom overall is neutral, as the number of protons (positive charge) is equal to the number of electrons (negative charge) in a neutral atom.
a proton has a positive charge
Zero. Neutrons do not have a charge; they are neutral.
A nickel ion with a +2 charge has lost 2 electrons. Since the atomic number of nickel is 28 and it is now a +2 ion, it has 26 electrons remaining (28 - 2 = 26).
If the oxidation is iii,charge also +3.Fluoride has -1 charge on it.
The answer is Ni3+
NiPO4 is Nickel (III) Phospate. The PO4 is a polyatomic particle which is called phosphate and has a charge of 3- and in this example Ni has a charge of 1+, so the charges are switched giving Ni a 3+ charge with stays positive and is written in the middle of the two names. [edit] Not quite... the nomenclature Nickel (III) indicates the Nickel has a charge of 3+. Nickel will either have a charge of 2+ or 3+, it can not have a charge of 1+, so I don't know what the original answerer was saying with switching charges bumping up the ionization of the Nickel. Basically, Ni3+ + PO43- -> NiPO4 OR if you are dealing with Nickel (II) Ni2+ + PO43- -> Ni3(PO4)2 which is also Nickel Phosphate Any way, I just wanted to correct the original post, but the answer to the original question is Nickel Phosphate, or as the original poster stated Nickel (III) Phosphate. -Mike
The answer is Ni3+
Nickel has an atomic number of 28- so if there aare only 26 electrons - 2 are missing and the ion will have a harge of 2+.
A proton has a positive charge.
A positive charge is a positive electrical charge. Particles with no charge are called neutral particles.
The charge of nickel when two electrons are lost is +2. When nickel loses two electrons, it becomes a cation with a charge of +2.
Protons are positive (each is +1) and electrons are negative (each is -1)
On their own metals have no charge. Metal ions have a positive charge.
