Lithium Bohr ModelSee more Lithium products. Lithium (atomic symbol: Li, atomic number: 3) is a Block S, Group 1, Period 2 element with an atomic weight of 6.94. The number of electrons in each of Lithium's shells is [2, 1] and its electron configuration is [He] 2s1. The lithium atom has a radius of 152 pm and a Van der Waals radius of 181 pm. Lithium was discovered by Johann Arvedson in 1817 and first isolated by William Thomas Brande in 1821. The origin of the name Lithium comes from the Greek wordlithose which means "stone." Lithium is a member of the alkali group of metals. It has the highest specific heat and electrochemical potential of any element on the period table and the lowest density of any elements that are solid at room temperature. Elemental LithiumCompared to other metals, it has one of the lowest boiling points. In its elemental form, lithium is soft enough to cut with a knife its silvery white appearance quickly darkens when exposed to air. Because of its high reactivity, elemental lithium does not occur in nature. Lithium is the key component of lithium-ion battery technology, which is becoming increasingly more prevalent in electronics.

Silicon Bohr MoleculeThe number of electrons in each of Silicon's shells is 2, 8, 4 and its electron configuration is [Ne] 3s2 3p2. The silicon atom has a radius of 111 pm and a Van der Waals radius of 210 pm. Silicon was discovered and first isolated by Jöns Jacob Berzelius in 1823. Silicon makes up 25.7% of the earth's crust, by weight, and is the second most abundant element, exceeded only by oxygen. The metalloid is rarely found in pure crystal form and is usually produced from the iron-silicon alloy ferrosilicon. Elemental SiliconSilica (or silicon dioxide), as sand, is a principal ingredient of glass, one of the most inexpensive of materials with excellent mechanical, optical, thermal, and electrical properties. Ultra high purity silicon can be doped with boron, gallium, phosphorus, or arsenic to produce silicon for use in transistors, solar cells, rectifiers, and other solid-state devices which are used extensively in the electronics industry.The name Silicon originates from the Latin word silex which means flint or hard stone.
