Quick answerTitanium (Ti) is a transition metal with atomic number 22 and an atomic mass of 47.867 (2023), in group 4, period 4. It was discovered by William Gregor in 1791. It is used for jet engines and medical implants. Its electron configuration is [Ar] 3d2 4s2.
Titanium is as strong as steel at half the weight, which is why it builds jet engines, hip implants, and deep-sea submarines.
