Nickel Element in Periodic Table | Atomic Number Atomic Mass

Nickel Element:

The chemical element Nickel is a silvery-white lustrous metal with a slight golden tinge. It is represented by the symbol Ni and atomic number is 28. Ni belongs to the d-block, and the member of the group 10 and period 4 in the periodic table. Ni occurs rarely free in nature. Instead it is found in ores such as pentlandite, pyrrhotite, and garnierite, millerite and niccolite. Ni contains 23 isotopes whose half-lives are known, with mass numbers 52 to 76. Naturally occurring nickel is a mixture of five stable isotopes; ⁵⁸Ni, ⁶⁰Ni, ⁶¹Ni, ⁶²Ni and ⁶⁴Ni, with ⁵⁸Ni being the most abundant.

Uses Of Nickel Element:

• Nickel is mainly used in making alloys such as stainless steel.
• Ni- steel alloy is used to make armor plate, vaults and machine parts.
• Nickel-copper alloy is used to make pipes that are used in desalination plants, which convert seawater into fresh water.
• It is used in making of rechargeable nickel-cadmium batteries and nickel-metal hydride batteries used in hybrid vehicles and also used in the manufacture of Alnico magnets.
• Ni also used in making of coins.
• Finely divided nickel is used as a catalyst for hydrogenating vegetable oils.
• Adding nickel to glass gives it a green colour.
