Cadmium Element in Periodic Table | Atomic Number Atomic Mass

Cadmium Element:

Cadmium is a chemical element and it is a member of group 12 and period 5 in the periodic table. The atomic number of cadmium is 48 and it is indicated by symbol Cd. Cd is a soft, malleable, ductile, bluish –white divalent metal. Cd is chemically similar to zinc and mercury. Cadmium occurs as a minor component in most zinc ores and is a bye-product of zinc production.

Uses of Cadmium Element:

• Cd is used in rechargeable nickel-cadmium batteries.
• It  was used to electroplate steel and protect it from corrosion.
•  Cadmium absorbs neutrons and so is used in rods in nuclear reactors to control atomic fission.
• Other uses of cadmium include phosphors in cathode ray tube color TV sets, orange and yellow and red pigments.
