Origin of 'Li'
Main points about word origin
- The name comes from the Greek word 'lithos', which means 'stone'.
- It was first discovered by Swedish chemist Johan August Arfwedson in 1817 while he was looking at a mineral called petalite.
The name 'lithium' is derived from the Greek word 'lithos', which means stone, referring to the mineral from which it was first isolated. Lithium was discovered in 1817 by the Swedish chemist Johan August Arfwedson, who found it in petalite, a mineral. It was isolated in its pure form in 1855 by the chemist Robert Bunsen and the physicist Gustav Kirchhoff through the process of electrolysis. Lithium is the third element on the periodic table and is a member of the alkali metals group. It is primarily obtained from mineral spodumene and salt lake brines. Today, lithium has significant applications in rechargeable batteries for mobile phones, laptops, and electric vehicles, as well as in mental health medications known for mood stabilization.
