Lithium (Li)

Lithium was discovered by a Swedish chemist Johan August Arfvedson in 1817 while analyzing a mineral called
petalite (LiAlSi₄O₁₀).
While Arfvedson identified lithium as a new element, he was unable to isolate it in its pure form. The pure metal
was first isolated in 1821, by English chemist William Thomas Brande using electrolysis.

The name Lithium comes from the Greek word lithos, meaning stone, because it was first found in minerals, unlike
sodium and potassium, which were discovered in ashes.
