What is Nickel?

  • Nickel is a transition metal, with an atomic number of 28, located in the fourth period/row on the periodic table of elements. It is an essential nutrient for the body but it’s over intake can cause harm. Humans can get the infection by breathing in infected air or drinking such water or eating such food or smoking cigarettes. Too much of nickel consumption can cause Lung cancer, Nose cancer, Larynx cancer, and Prostate cancer.

Uses Of Nickel

  • The most crucial use of this element is that it is used to make coins.
  • It is used in making wires.
  • It is used in gas turbines and rocket engines as it has the capability to resist corrosion even at high temperature.
  • It is used to make a variety of alloys which are further used to make armour plating, nails, or pipes.
  • Monel (alloys of nickel and copper), is a hard compound and can resist corrosion by seawater. Hence, it is used in propeller shaft in boats and desalination plants.

Properties Of Nickel

  • Nickel is silvery-white, hard, malleable, and ductile metal.
  • It is a good conductor of heat and electricity.
  • It is bivalent, that is it has a valency of two.
  • The metal dissolves slowly in dilute acids.
  • It’s melting point is 1453 °C and boiling point is 2913 °C.

Certain Facts About Nickel

  • As it is radioactive metal, it is toxic and harmful to life.
  • The compound of 99Tc is very contaminative in nature and hazardous for life.
  • One must use a safety glove box while handling the chemical.
