Curie Point of Nickel
The magnetic properties of nickel change when it is heated above its Curie point.
nickel
Paramagnetism: Compounds - Nickel(II) Sulfate Hexahydrate
Nickel(II) sulfate hexahydrate, NiSO4·6H2O, eventually swings toward a magnet.
Paramagnetism: Compounds - Hexaamminenickel(II) Chloride
Hexaamminenickel(II) chloride, [Ni(NH3)6]Cl2, is attracted weakly to the poles of a magnet.
Reaction of nickel with iodine
Powdered nickel and powdered iodine are mixed together. Adding drops of water to the mixture fails to initiate a reaction.
