Bismuth is a chemical element; it has 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.
Bismuth atoms are shown as grey, oxygen red, chlorine green. Bismuth oxychloride (BiOCl) and bismuth oxynitrate (BiONO 3) stoichiometrically appear simple anionic salts of the bismuthyl (III) cation (BiO +), which commonly occurs in aqueous bismuth compounds. However, in the case of BiOCl, the salt crystal forms alternating plates of Bi, O, and ...
Isotopes of bismuth (83Bi) Bismuth (83 Bi) has 41 known isotopes, ranging from 184 Bi to 224 Bi. Bismuth has no stable isotopes, but does have one very long-lived isotope; thus, the standard atomic weight can be given as 208.980 40(1). Although bismuth-209 is now known to be radioactive, it has classically been considered to be a stable isotope ...
Lead-bismuth produces a considerable amount of polonium-210 from neutron activation of bismuth-209. This radioactive element will dissolve in the lead-bismuth, and is an alpha emitter with a half-life of 138.38 days. This can seriously complicate maintenance and pose a severe plant alpha-contamination problem.
Bismuth vanadate is a bright yellow powder and may have a slight green tint. When used as a pigment it has a high Chroma and excellent hiding power. In nature, bismuth vanadate can be found as the mineral pucherite, clinobisvanite, and dreyerite depending on the particular polymorph formed. Its synthesis was first recorded in a pharmaceutical ...
Bismuth telluride (Bi2Te3) is a gray powder that is a compound of bismuth and tellurium also known as bismuth (III) telluride. It is a semiconductor, which, when alloyed with antimony or selenium, is an efficient thermoelectric material for refrigeration or portable power generation. Bi2Te3 is a topological insulator, and thus exhibits ...
Infobox references. Bismuth chloride (or butter of bismuth) is an inorganic compound with the chemical formula BiCl 3. It is a covalent compound and is the common source of the Bi 3+ ion. In the gas phase and in the crystal, the species adopts a pyramidal structure, in accord with VSEPR theory.
Bismuth / ˈ b ɪ z m ə θ / is a chemical element that has the symbol Bi and atomic number 83. This heavy, brittle, white crystalline trivalent other metal has a pink tinge and chemically resembles arsenic and antimony. Of all the metals, it is the most naturally diamagnetic, and only mercury has a lower thermal conductivity. It is also ...
