bismuth

Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a post-transition metal that is chemically similar to arsenic and antimony. Bismuth often has a silvery-white colour, but it can also be reddish-brown.

Bismuth is a relatively rare element, making up only about 0.00005% of the Earth's crust. It is found in small amounts in some minerals, such as bismuthinite and bismuth ochre.

Bismuth has a variety of properties that make it useful in different applications. It is a good conductor of heat and electricity, and it is also a relatively soft metal. Bismuth is also non-toxic, which makes it safe to use in some medical applications.

Some of the uses of bismuth include:

• Medication: Bismuth is used in some medications, such as Pepto-Bismol, to treat stomach upset and diarrhoea.
• Alloys: Bismuth is often alloyed with other metals, such as lead and tin, to create materials with specific properties. For example, bismuth-tin alloys are used in low-melting point solders.
• Glazes: Bismuth is used in some glazes to create a blue or red colour.
• Cosmetics: Bismuth is used in some cosmetics, such as lipsticks, to give them a pearlescent or metallic finish.
