2. Characteristics of Nickel It is one of only four elements that are magnetic at or near room temperature. Nickel discovered by Cronstedt in 1751 has: – Atomic number of 28 – Atomic mass of 58.71 – Number of proton – Number of electrons – Density of 8.9g

3. Characteristics of Nickel It belongs to group 10 (VIIIB) Nickel is classified as a transition metal. Transition metals are elements between Groups 2 (metals) and 13 (non-metals) in the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. Nickel is closely related to iron, cobalt, copper, and zinc.

4. Characteristics of Nickel Physical: Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is hard, Malleable, ductile, somewhat ferromagnetic. Belong to the iron-cobalt group of metals and is chiefly valuable for the alloys it forms.

5. Characteristics of Nickel Chemical: Nickel is a relatively unreactive element. At room temperature, it does not combine with oxygen or water or dissolve in most acids. At higher temperatures, it becomes more active, – e.g. nickel burns in oxygen to form nickel oxide(NiO). It also reacts with steam to give nickel oxide and hydrogen gas. Fair conductor of heat and electricity. It is explosive in air

6. Important uses of Nickel It is extensively used for making stainless steel. In armor plates and burglar-proof vaults. The metal is corrosion- resistant hence can be useful in alloys, as a plating, in the manufacture of coins, magnets and common household utensils,

7. Important uses of Nickel Nickel is also very popular in the manufacture of batteries. Nickel is also used in electroplating, a process by which a thin layer of one metal is laid down on top of a second metal. It is also used to make heavy machinery and large containers in which large-scale chemical reactions are carried out.

8. Important uses of Nickel It is also used for plating and as a green tint in glass. Nickel is pre-eminently an alloy metal, and its chief use is in the nickel steels and nickel cast irons, of which there are many varieties.

9. Description of Nickel characteristics It was voted allergen of the year in 2008 by the American Contact Dermatitis Society. In nature it occurs combined with sulfur in millerite. – Millerite means a nickel sulfide mineral usually occurring in long hairlike crystals and sometimes used as a nickel ore. Nickel is an important cause of contact allergy, partly due to its use in jewelery intended for pierced ears. Nickel is a relatively unreactive element. Mallable, meaning it is capable of being hammered into thin sheets.

10. Description of Nickel characteristics Ductile meaning it is capable of being drawn into thin wires. At room temperature, it does not combine with oxygen or water or dissolve in most At higher temperatures, it becomes more active. – For example, nickel burns in oxygen to form nickel oxide (NiO): It also reacts with steam to give nickel oxide and hydrogen gas:
