The Versatile and Essential Element: Titanium

Titanium is a strong, lightweight element with the atomic number 22 and symbol Ti. Named after Greek Titans, it was discovered by William Gregor. Titanium is used in alloys for aircraft, spacecraft, and missiles due to its strength and low density. It resists corrosion, making it ideal for power plants and marine applications. In medicine, titanium is biocompatible, used in implants and surgical tools. It's also popular in jewelry for its durability and inertness. Titanium dioxide, a common compound, is used in paints, coatings, and sunscreens for its brightness and UV protection.
