Lithium (from Ancient Greek λίθος (líthos) 'stone') is a chemical element; it has symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element.

Feb 17, 2025 · Lithium, chemical element of Group 1 (Ia) in the periodic table, the alkali metal group, lightest of the solid elements. The metal itself—which is soft, white, and lustrous—and several of its alloys and compounds are produced on an industrial scale.

The term "lithium battery" refers to a family of different lithium-metal chemistries, comprising many types of cathodes and electrolytes but all with metallic lithium as the anode. The battery requires from 0.15 to 0.3 kg (5 to 10 oz) of lithium per kWh.

Lithium is considered a metal due to its electron configuration, which allows it to easily conduct electricity. It has a silvery-white appearance with a metallic sheen, another metal characteristic. So no, lithium is not a metalloid.

Lithium is an alkali metal that was discovered in 1817. It is a highly reactive metal and is used in variety of applications including, rechargeable batteries and rocket fuel due to its light weight and very high boiling point.

Nov 3, 2019 · Lithium is the third element in the periodic table, with three protons and the element symbol Li. It has an atomic mass of 6.941. Natural lithium is a mixture of two stable isotopes, lithium-6 and lithium-7. Lithium-7 accounts for over 92% of the natural abundance of the element. Lithium is an alkali metal. It's silver-white in pure form and is ...

Lithium (pronounced as LITH-ee-em) is a soft metal with a silver appearance, represented by the chemical symbol Li. It belongs to the family of alkali metals and reacts spontaneously with water. Out of its seven isotopes with mass numbers ranging from 5 to 11, only Li-6 and Li-7 have a natural existence.

May 17, 2018 · Lithium is a soft, silvery alkali metal and has the lowest density of any metal. The word "lithium" is derived from "lithos" (Greek for "stone"). Johan A. Arfvedson discovered lithium in Stockholm, Sweden, in 1817. Humphry Davy isolated it via electrolysis in 1818.
