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.
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 ...
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 ...
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.
Bismutite or bismuthite is a bismuth carbonate mineral with formula Bi 2 (CO 3)O 2 (bismuth subcarbonate). Bismutite occurs as an oxidation product of other bismuth minerals such as bismuthinite and native bismuth in hydrothermal veins and pegmatites. [3] It crystallizes in the orthorhombic system and typically occurs as earthy to fibrous masses.
Bismuthyl — inorganic oxygen-containing singly charged ion with the chemical formula BiO +, is an oxycation of bismuth in the +3 oxidation state. Most often it is formed during the hydrolysis of trivalent bismuth salts, primarily nitrate, chloride and other halides. In chemical compounds, bismuthyl plays the role of a monovalent cation.
Bismuth-209. Bismuth-209 (209 Bi) is an isotope of bismuth, with the longest known half-life of any radioisotope that undergoes α-decay (alpha decay). It has 83 protons and a magic number [ 2 ] of 126 neutrons, [ 2 ] and an atomic mass of 208.9803987 amu (atomic mass units). Primordial bismuth consists entirely of this isotope.
Bismuthinite is a mineral consisting of bismuth sulfide (Bi 2 S 3). It is an important ore for bismuth. The crystals are steel-grey to off-white with a metallic luster. It is soft enough to be scratched with a fingernail and rather dense. Bismuthinite forms a series with the lead, copper, bismuth mineral aikinite (Pb Cu Bi S 3). [4] It occurs ...
