Methyllithium Lithium Bromide Complex

See more Bromine products. Bromine (atomic symbol: Br, atomic number: 35) is a Block P, Group 17, Period 4 element. Its electron configuration is [Ar]4s²3d¹⁰4p⁵. The bromine atom has a radius of 102 pm and its Van der Waals radius is 183 pm. In its elemental form, bromine has a red-brown appearance. Bromine does not occur by itself in nature; it is found as colorless soluble crystalline mineral halide salts. Bromine was discovered and first isolated by Antoine Jérôme Balard and Leopold Gmelin in 1825-1826.

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. Compared 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.
