How did lithium get its symbol?

Answer 1

I don't know for sure. I do know that Lithium's symbol (Li) came from one of two chemists: either John Dalton, who invented the system of using symbols to describe elements, or J. A. Arfvedson, who discovered and named the element. Both chemists lived at about the same time.

Answer 2

The symbol for lithium, Li, comes from its Latin name "lithium". This name was derived from the Greek word "lithos", meaning stone, as lithium compounds were first discovered in minerals.
