Titanium 47.9 Titanium was discovered by William Gregor in 1791.
Titanium is silver-white metallic element used principally to make light, strong alloys.
Titanium is one of the transition elements of the periodic table. The atomic number of Titanium is 22. Titanium was discovered in 1791 in the mineral menachanite by the British clergyman William Gregor, who named the new element menachite. Pure titanium is soluble in concentrated acids, such as sulfuric and hydrofluoric acids, and insoluble in water. The metal is extremely brittle when cold, but is readily malleable and ductile at a low red heat.
