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 etymology. The name possibly comes from obsolete German Bismuth, Wismut, Wissmuth (early 16th century), perhaps related to Old High German hwiz ("white"). [10]
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 .
Unlike the lighter pnictogens nitrogen, phosphorus, and arsenic, but similar to antimony, bismuth does not form a stable hydride. Bismuth hydride, bismuthine (BiH 3), is an endothermic compound that spontaneously decomposes at room temperature. It is stable only below −60 °C. [5] Bismuthides are intermetallic compounds between bismuth and ...
Bismuth does not. Bismuth melts easily and if kept melted, calcinates forming a yellow powder. Bismuth amalgamates with Mercury; the regulus of Cobalt does not at all. Bismuth dissolved in nitric acid and with aqua regia and gives a white precipitate when put in pure water. The regulus of Cobalt needs alkalies to precipitate, and then forms ...
Bismuth oxychloride is an inorganic compound of bismuth with the formula Bi O Cl. It is a lustrous white solid used since antiquity, notably in ancient Egypt . Light wave interference from its plate-like structure gives a pearly iridescent light reflectivity similar to nacre .
It has bismuth in its +5 oxidation state. It is a very strong oxidizing agent. It reacts with hot water to make bismuth(III) oxide and oxygen. It also reacts with acids. Sodium bismuthate is the most common bismuthate. It is one of the few sodium compounds that does not dissolve in water. [1]
Bismuth subcarbonate can be attained from the reaction between bismuth nanoparticles and the atmospheric carbon dioxide (CO 2) dissolved in water. [6] Bismuth subcarbonate has the tendency to form nanoplates, but it can be also obtained as small round nanospheres (with controlled size) when it is grown in the presence of halloysite nanotubes.

Previously, it was believed that bismuthyl plays almost the main role in the geochemistry of bismuth and metamorphic processes taking place in a liquid medium. Already in ore waters, bismuth and its main compounds are oxidized, forming a sparingly soluble oxychloride — bismoclite, which, when mixed with bicarbonate background waters, is replaced by an even more sparingly soluble — bismuthite.
