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.

A lithium atom is an atom of the chemical element lithium. Stable lithium is composed of three electrons bound by the electromagnetic force to a nucleus containing three protons along with either three or four neutrons, depending on the isotope, held together by the strong force.

Jan 25, 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. Learn more about the occurrence and uses of lithium.

Lithium is a chemical element with symbol Li and atomic number 3. Classified as a n alkali metal, Lithium is a solid at room temperature. [He]2s 1. J.C. Slater, J Chem Phys, 1964, 41 (10), 3199-3205. DOI:10.1063/1.1725697.

Is lithium a metal/nonmetal, discovery date, properties (atomic mass, how it looks like, melting point, boiling point, electron configuration), common uses, price

Lithium is the 3rd element in the periodic table and has a symbol of Li and atomic number of 3. It has an atomic weight of 6.940 and a mass number of 7. Lithium has three protons and four neutrons in its nucleus, and three electrons in two shells. It is located in group one, period two and block s of the periodic table. Socket silvery metal.

Jan 21, 2025 · Atomic Number: It has an atomic number of 3, placing it in the alkali metals group in the periodic table. Electronegativity: With an electronegativity of 0.98 on the Pauling scale, lithium tends to lose its one valence electron to form ionic compounds.

Lithium atoms have 3 electrons and the shell structure is 2.1. The ground state electron configuration of ground state gaseous neutral lithium is [He].2s 1 and the term symbol is 2 S 1/2.

Under normal conditions, all of the Group 1 (alakali metals) elements are based upon the bcc structure. The closest Li-Li separation is 304 pm implying a lithium metallic radius of 152 pm. This means that lithium is smaller than potassium.
