All nickel(II) salts are coloured.
For example: chromium, nickel, uranium salts.

Nickel carbonate is considered an inorganic compound. It is a chemical compound that contains nickel, carbon, and oxygen, and is typically formed through the reaction of nickel salts with carbonate compounds.
All salts can form crystals.
Since 1966, Australia has used the Australian Dollar consisting of 100 cents. The silver coloured coins are made from a copper-nickel alloy and the gold coloured coins are made from a copper-nickel-aluminium alloy. Commenced in 1992 and completed in 1996, all Australian banknotes were changed over from the traditional paper construction, to a polymer compound.
Transition metals are most likely to form colored salts due to their partially filled d or f orbitals, which allow for absorption of certain wavelengths of light. For example, salts of chromium, copper, iron, and cobalt often exhibit distinct colors due to the presence of unpaired electrons in their outer energy levels.
Some nickel salts can cause serious dermatitis or ulcers, so this project should be undertaken with care. Seek expert advice.
They are all transition elements, so all are fairly unreactive, form coloured compounds and are hard and strong elements, they can be used to make alloys.
Not all salts are neutral in water solutions.
All salts are crystallized.
Practically all salts contain a metal; exceptions, for example, are ammonium salts.
Salts are ionic compounds.
