Properties of bismuth
Bismuth belongs to the group of metallic elements known as the p-block metals that are located next to the metalloids or semimetals in the periodic table. These types of elements tend to be soft and have low melting points, properties that can also be attributed to bismuth, since it is part of this group of elements.
The state of bismuth in its natural form is solid. Bismuth is a bright white, red-looking chemical element and belongs to the p-block group of metals. The atomic number of bismuth is 83. The chemical symbol for bismuth is Bi. The melting point of bismuth is 544.4 degrees Kelvin or 272.25 degrees Celsius, or degrees Celsius. The boiling point of bismuth is 1837 degrees Kelvin or 1564.85 degrees Celsius or degrees Centigrade.
Atomic properties of bismuth
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. Regarding the position where to find bismuth within the periodic table of elements, bismuth is found in group 15 and period 6. Bismuth has an atomic mass of 208.98038 u.
The electron configuration of bismuth is [Xe] 4f14 5d10 6s2 6p3. The electronic configuration of the elements determines the way in which the electrons are structured in the atoms of an element. The mean radius of bismuth is 160 pm, its atomic radius or Bohr radius is 143 pm, and its covalent radius is 146 pm.

History
From the German Weisse Masse, meaning white mass; later Wisuth and Bisemutum. In early times bismuth was confused with tin and lead. Claude Geoffroy the Younger showed it to be distinct from lead in 1753.
Properties
It is a white, crystalline, brittle metal with a pinkish tinge. It occurs in a native state. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal, except mercury. It has a high electrical resistance, and has the highest Hall effect of any metal (i.e., greatest increase in electrical resistance when placed in a magnetic field).
Sources
The most important ores are bismuthinite or bismuth glance and bismite. Peru, Japan, Mexico, Bolivia, and Canada are major bismuth producers. Much of the bismuth produced in the U.S. is obtained as a by-product in refining lead, copper, tin, silver, and gold ores.
Uses
Number Of Protons In Bismuth
'Bismanol' is a permanent magnet of high coercive force, made of MnBi, by the U.S. Naval Surface Weapons Center. Bismuth expands 3.32% on solidification. This property makes bismuth alloys particularly suited to the making of sharp castings of objects subject to damage by high temperatures. With other metals such as tin, cadmium, etc., bismuth forms low-melting alloys which are extensively used for safety devices in fire detection and extinguishing systems. Bismuth is used in producing malleable irons and is finding use as a catalyst for making acrylic fibers. When bismuth is heated in air it burns with a blue flame, forming yellow fumes of the oxide. The metal is also used as a thermocoupling material, and has found application as a carrier for 235U or 233U fuel in nuclear reactors. Its soluble salts are characterized by forming unsoluble basic salts on the addition of water, a property sometimes used in detection work. Bismuth oxychloride is used extensively in cosmetics. Bismuth subnitrate and subcarbonate are used in medicine.
