Titanium is a chemical element with atomic number 22 and symbol Ti. Here are some of its primary chemical properties:
1. Titanium is a transition metal.
2. This element exhibits multiple oxidation states, but the +4 oxidation state is most common.
3. It reacts with oxygen to form titanium dioxide.
4. Titanium is resistant to corrosion in sea water, aqua regia (a mixture of hydrochloric acid and nitric acid) and chlorine.
5. It is not as resistant to acids as its reputation might suggest. For example, it is attacked by concentrated sulfuric and hydrofluoric acids.
6. At higher temperatures, it can react vigorously with other common elements such as nitrogen and hydrogen. This leads to the formation of brittle, hard, titanium nitride and titanium hydride layers on the surface.
7. Titanium can catch fire when heated in air, and in powdered form, it can be a fire hazard.
8. It is paramagnetic, meaning it is weakly attracted to magnetic fields but does not retain any magnetism once the field is removed.
9. Titanium also forms alloys with many other elements, including aluminum, iron, and molybdenum. These alloys are typically strong and lightweight, making them ideal for aerospace applications.
