Bismuth (/ˈbɪzməθ/) is a chemical element with the symbol Bi and atomic number 83. It is a dense, silvery-white metal that is commonly used in cosmetics, alloys, and medicines. The spelling of "bismuth" is straightforward, with a pronounced "b" followed by a short "i" sound, then "s" and "m" blend together, and the final syllable has a long "u" sound and ends with "th". The IPA phonetic transcription of this word helps to clarify the correct pronunciation for those unfamiliar with the word.
Bismuth is a chemical element with the symbol Bi and atomic number 83. It belongs to the group of post-transition metals and is classified as a heavy metal. Bismuth is characterized by a distinctly lustrous silver-white color and exhibits an iridescent oxide tarnish. It is the most naturally diamagnetic element and has relatively low thermal and electrical conductivity.
This element is widely used in various applications and industries, including pharmaceuticals, cosmetics, and metallurgy. Bismuth compounds have been used for centuries for their medicinal properties, particularly in antacid medications to alleviate symptoms of gastrointestinal disorders. Additionally, bismuth is employed in the manufacture of cosmetics, pigments, and paints due to its ability to produce vibrant shades. It also finds application in the production of certain alloys used in industries like automotive and aerospace.
From a historical perspective, bismuth was known to humans since ancient times and often confused with tin or lead due to its similar appearance. It was isolated as a pure metal by Claude François Geoffroy in the late 18th century. Bismuth is abundantly available in the Earth's crust, primarily sourced from minerals such as bismuthinite, bismite, and bismoclite.
In summary, bismuth is a metallic chemical element characterized by a lustrous silver-white color. It finds extensive applications in various sectors ranging from medicine to cosmetics, owing to its unique properties and versatility.

The word "bismuth" has its origins in late Latin "bisemutum" or "bisemutium". It was derived from the German "wismuth", which can be traced back to the Old High German "wisemut". The German term could have been influenced by another word, "weißmuth", meaning "white lead". Ultimately, the word "bismuth" is thought to have its roots in the combination of "bis" (meaning "twice" in Latin) and "mutum" (meaning "mute, silent"). This is because bismuth was often confused with lead due to its similar appearance and was originally considered to be a form of lead that did not react to fire.
