Bismuth Element in Periodic Table | Atomic Number Atomic Mass


Bismuth Element:

Bismuth is an element in the 15th group and 6th period of the periodic table. Its atomic number is 83 and it is represented by the symbol Bi. It is a post-transitional element. Bismuth is a brittle metal with a silvery white colour and shiny surface and a yellowish or pinkish tinge. It occurs naturally but found in small quantities throughout Earth's crust both as a pure metal and combined with other elements in various compounds. The largest source of bismuth is found in the ores such as bismuthinite and bismite. It has only one naturally occurring isotope, bismuth-209.

Uses Of Bismuth Element:

  • Bismuth is used in alloys with tin or cadmium and is also used in fire detectors and extinguishers, electric fuses and solders.
  • Bismuth oxide is used for cosmetics and paints.
  • Basic bismuth carbonate is used for treatment of indigestion as ‘bismuth mixture’ in liquid form or even as tablets.
