6. Hardness of Nickel. Whenever the definition of metal pops into one's head, there are a few physical properties that come to mind. Lustre, in addition to physical state, are a few examples. However, the hardness of the metal in question is probably the most immediate thought. By and large, most metals are rigid by composition.

The metallurgy of nickel is complicated in its details, many of which vary widely, according to the particular ore being processed. In general, the ore is transformed to dinickel trisulfide, Ni 2 S 3 (with nickel in the +3 oxidation state), which is roasted in air to give nickel oxide, NiO (+2 state), which is then reduced with carbon to obtain the metal.

The Mohs scale is a system used to rank materials on their hardness, which is graded using numbers from 1 to 10. It can be used to compare gemstones, metals and other materials, and evaluate their relative durability. Where a metal stands on the Mohs scale indicates which other metals can scratch it. For example, gold's hardness rating is 2.5 ...
