Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a post-transition metal and one of the pnictogens, with chemical properties resembling its lighter group 15 siblings arsenic and antimony. Elemental bismuth occurs naturally, and its sulfide and oxide forms are important commercial ores. … See more Bismuth compounds account for about half the global production of bismuth. They are used in cosmetics; pigments; and a few pharmaceuticals, notably bismuth subsalicylate, used to treat diarrhea. Bismuth's unusual … See more Physical characteristics Bismuth is a brittle metal with a dark, silver-pink hue, often with an iridescent oxide tarnish showing many colors from yellow to blue. The spiral, stair-stepped structure of bismuth crystals is the result of a higher growth … See more In the Earth's crust, bismuth is about twice as abundant as gold. The most important ores of bismuth are bismuthinite and bismite. Native bismuth is known from Australia, Bolivia, and China. See more See also bismuthia, a rare dermatological condition that results from the prolonged use of bismuth. Scientific literature indicates that some of the compounds of … See more Bismuth metal has been known since ancient times and it was one of the first 10 metals to have been discovered. The name bismuth dates to around 1665 and is of uncertain … See more Bismuth forms trivalent and pentavalent compounds, the trivalent ones being more common. Many of its chemical properties are similar to those of arsenic and antimony, although they are less toxic than derivatives of those lighter elements. Oxides and sulfides See more Bismuth has few commercial applications, and those applications that use it generally require small quantities relative to other raw materials. In … See more WebIt can melt quite easily and it can grow stunning little ziggurat like crystals by cooling it slowly from melt. It is easy.

How to Make Bismuth Crystals From Pepto-Bismol

WebThe following information is given for bismuth at 1 atm : boiling point = 1627∘C melting point = 271∘C specific heat solid = 0.126 J/g∘C specific heat liquid = 0.151 J/g∘C ΔHvap (1627∘C) = 172 kJ/mol ΔHfus (27∘C)= 11.0 kJ/mol What is ΔH in kJ for the process of freezing a 24.4 g sample of liquid bismuth at its normal melting ... WebBismuth is thus a useful component of type-metal alloys, which make neat, clean castings; and it is an important ingredient of low-melting alloys, called fusible alloys, which have a large variety of applications, especially in fire-detection equipment. A bismuth–manganese alloy has been found effective as a permanent magnet. WebBismuth telluride is a well-studied topological insulator. Its physical properties have been shown to change at highly reduced thicknesses, when its conducting surface states are exposed and isolated.
