Planetary Bohr Model of Titanium (Ti)
Description
Shiny, dark-gray metal. Ninth most abundant element in the earth's crust (5700 ppm). It can be highly polished, and is relatively immune to tarnishing.
Uses
Since it is strong and resists acids it is used in many alloys. Titanium dioxide (TiO2), a white pigment that covers surfaces very well, is used in paint, rubber, paper and many others.
Sources
Usually occurs in the minerals ilmenite (FeTiO3) or rutile (TiO2). Also in Titaniferous magnetite, titanite (CaTiSiO5), and iron ores. Pure metal produced by heating TiO2 with C and Cl2 to produce TiCl4 then heated with Mg gas in Ar atmosphere.
Pronounciation (English)
tie-TAY-ni-em
