What does it look, feel, taste, or smell like?
Lithium is a very soft silvery metal, and can be cut with a knife just like butter. Lithium tarnishes quickly in the air, and will turn black within seconds. It is the lightest metal. Its density is only 0.53 g/cm^3, about the same as pine wood. Lithium is light enough to float in water. But like all alkali metals, it also reacts violently with water to form lithium hydroxide (a base) and hydrogen gas. So don't expect any lithium bath toys.
How was it discovered?
Lithium was discovered in Sweden in 1817 by Johann August Arfvedson.
Where did its name come from?
The name "lithium" comes from the Greek name lithos which means "stone."
Where is it found?
It is found in mineral springs and is found in most igneous rocks.
What are its uses?
Lithium is used to transfer heat from one object to the next. Some things lithium is used in are glasses, organic compounds, and ceramics. Because it is such a good conductor of electricity, it is used in batteries as well.
Is it dangerous?
Lithium is not dangerous but it is highly reactive.
