Biography and Composition of Titanium
Titanium, represented by the symbol Ti and atomic number 22, is a transition metal known for its low density and high strength. It is lustrous and exhibits a white-silver appearance. Titanium is as strong as steel but less dense, making it an ideal choice for applications where weight is a critical factor.
The discovery of titanium dates back to 1791 when William Gregor, an amateur geologist, identified it in a black sand near Cornwall, England. However, it wasn't until 1795 that the German chemist Martin Heinrich Klaproth named it titanium, after the Titans of Greek mythology, because of its formidable nature.
