Physical properties. Sulfur forms several polyatomic molecules. The best-known allotrope is octasulfur, cyclo-S 8.The point group of cyclo-S 8 is D 4d and its dipole moment is 0 D. Octasulfur is a soft, bright-yellow solid that is odorless, but impure samples have an odor similar to that of matches. It melts at 115.21 °C (239.38 °F), boils at 444.6 °C (832.3 °F) and sublimes more or …

Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. Tin is a silvery-coloured metal. Tin is soft enough to be cut with little force and a bar of tin can be bent by hand with little effort. When bent, the so-called "tin cry" can be heard as a result of twinning in tin crystals; this trait is shared by indium, cadmium, zinc, and mercury in the solid state.
Titanium is a chemical element with the symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine.. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by …
A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). These properties are the result of the metallic bond between the ...

But historically, the prices of cobalt in the market have remained relatively stable except for the rapid price increases in the last 1970s. Known as the cobalt crisis, the period was preceded by the limited cobalt production capacity worldwide, cessation of sales by the U.S. government, and the issues of supply from the Zaire cobalt mining region, among others.
Ferroalloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese (Mn), aluminium (Al), or silicon (Si). They are used in the production of steels and alloys. The alloys impart distinctive qualities to steel and cast iron or serve important functions during production and are, therefore, closely associated with the iron and steel industry, the ...
The gemstones beryl and emerald are both forms of beryllium aluminium silicate, Be 3 Al 2 (SiO 3) 6.The French mineralogist Abbé René-Just Haüy thought they might harbour a new element, and he asked Nicholas Louis Vauquelin, to analyse them and he realised they harboured a new metal and he investigated it.
