Bismuth. Bismuth is a white, crystalline, brittle metal with a pinkish tinge. 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 (that is, the greatest increase in electrical resistance when placed in a magnetic field).

alloys of calcium with agent for aluminium, beryllium, copper, lead, and magnesium have some useful properties "getter" for residual gases in vacuum tubes, etc. quicklime (CaO) is made by heating limestone (CaCO 3) and changes into slaked lime, Ca(OH) 2, on the addition of water. It is a cheap base for the chemical industry with many uses.
Boron is never found free in nature. Two types of boron are found . Amorphous boron is a brown powder and metallic (crystalline) boron is black and hard and a weak conductor at room temperature. Pure boron is used as a dopant (a substance added to semiconductors to change how it behaves with electricity) in the semiconductor industry.
Beryllium is alloyed with nickel (2% beryllium, 98% nickel) to make springs, spot-welding electrodes and non-sparking tools. Other beryllium alloys are used in the windshield, brake disks and other structural components of the space shuttle. Beryllium oxide (BeO), a compound of beryllium, is used in the nuclear industry and in ceramics.
Emeralds and beryl were both known to early Egyptians but it was not realised until the end of the 18th century that they are the same mineral, now called beryllium aluminium silicate: [Be 3 Al 2 (SiO 3) 6].The element was recognised by M.-L. Vauquelin in 1798 in beryl and emeralds.
Beryllium-copper alloy is used in tools because it does not make sparks. At standard temperature and pressure, beryllium resists oxidation when exposed to oxygen. Beryllium is best known for the chemical compounds it forms. Beryllium combines with aluminium, silicon and oxygen to …
Beryllium sulfide, selenide and telluride are known, all having the zincblende structure. Beryllium nitride, Be 3 N 2 is a high-melting-point compound which is readily hydrolyzed. Beryllium azide, BeN 6 is known and beryllium phosphide, Be 3 P 2 has a similar structure to Be 3 N 2.
Bismuth was discovered by an unknown alchemist around 1400 AD. Later that century it was alloyed with lead to make cast type for printers and decorated caskets were being crafted in the metal. Bismuth was often confused with lead; it was likewise a heavy metal and melted at a relatively low temperature making it easy to work.
Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a pentavalent post-transition metal and one of the pnictogens with chemical properties resembling its lighter homologs arsenic and antimony.Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores. The free element is 86% as dense as lead.It is a brittle metal with a silvery ...
Bismuth has been known since the fifteenth century. In 1753, French chemist Claude Geoffroy the Younger established that it was an element in its own right rather than a form of lead.. Bismuth is considered to be stable, although it is actually radioactive with an extremely slow rate of decay.

Beryllium also has high thermal conductivity and is nonmagnetic. Uses of Beryllium. Unlike most metals, beryllium is virtually transparent to x-rays and hence it is used in radiation windows for x-ray tubes. Beryllium alloys are used in the aerospace industry as light-weight materials for high performance aircraft, satellites and spacecraft.

Beryllium is a silvery white metal. The surface of beryllium metal is covered with a thin layer of oxide that helps protect the metal from attack by air. It does not oxidize in air even at 600°C. However, powdered beryllium metal does burn in air to give a mixture of white beryllium oxide, BeO, and beryllium nitride, Be 3 N 2. Beryllium oxide ...
Boron also occurs as orthoboric acid in some volcanic spring waters. Isotopes: 11 whose half-lives are known, with mass numbers 7 to 17. Naturally occurring boron is a mixture of its two stable isotopes and they are found in the percentages shown: ... Barium – Berkelium – Beryllium – Bismuth – Bohrium – Boron – Bromine. C.

Boron is a chemical element with the symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar system and in the Earth's crust. Boron is concentrated on Earth by the water-solubility of its more common naturally occurring compounds, the borate minerals.
