What element has the symbol 'Li'?

The story behind the answer

Lithium is the correct answer because the chemical symbol Li stands for Lithium, the lightest metal and third element on the periodic table. The other options have different symbols: Lead is Pb (from Latin plumbum), Lanthanum is La, and Lutetium is Lu. Lithium is a soft, highly reactive alkali metal that’s stored in oil and even floats on water.

Fun context: “Lithium” comes from the Greek lithos, meaning “stone,” because it was first discovered in mineral form. It’s vital in modern life—powering rechargeable lithium-ion batteries and used in certain medications. Memory tip: Li = LIght metal and LIthium-ion batteries. Or think “LIttle element #3” to link Li with its small size and early position on the table.
