Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
Curium bromide is an ionic compound composed of Cm 3+ and Br −, appearing as a colorless solid. It is orthorhombic, with space group Cmcm (No. 63) and lattice parameters a = 405 pm, b = 1266 pm and c = 912 pm. [ 5 ] Its crystal structure is isostructural with plutonium(III) bromide .
Cadmium bromide is the inorganic compound with the formula CdBr 2. It is a white hygroscopic solid. It is a white hygroscopic solid. It also can be obtained as a mono- and tetrahydrate. [ 2 ]
An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.
Cannizzaro's chemical interests had originally centered on natural products and on reactions of aromatic compounds; in 1853 he discovered that when benzaldehyde is treated with concentrated base, both benzoic acid and benzyl alcohol are produced—a phenomenon known today as the Cannizzaro reaction. In his 1858 pamphlet, Cannizzaro showed that ...
Radium bromide is the bromide salt of radium, with the formula RaBr 2.It is produced during the process of separating radium from uranium ore.This inorganic compound was discovered by Pierre and Marie Curie in 1898, and the discovery sparked a huge interest in radiochemistry and radiotherapy.
Bromide compounds, especially potassium bromide, were frequently used as sedatives in the 19th and early 20th centuries. Their use in over-the-counter sedatives and headache remedies (such as Bromo-Seltzer ) in the United States extended to 1975 when bromides were withdrawn as ingredients due to chronic toxicity .

Francium was the last element to be discovered in nature, rather than synthesized in the lab, although four of the "synthetic" elements that were discovered later (plutonium, neptunium, astatine, and promethium) were eventually found in trace amounts in nature as well. [178]
