See also:NEWLANDS, See also:JOHN See also:ALEXANDER REINA (1838-1898) , See also:English chemist, was See also:born in 1838. He was one of the first, if not quite the first, to propound the conception of periodicity among the chemical elements. His earliest contribution to the question took the See also:form of a See also:letter published in the Chemical See also:News in See also:February 1863. In the succeeding See also:year he showed, in the same See also:journal, that if the elements be arranged in the See also:- ORDER
- ORDER (through Fr. ordre, for earlier ordene, from Lat. ordo, ordinis, rank, service, arrangement; the ultimate source is generally taken to be the root seen in Lat. oriri, rise, arise, begin; cf. " origin ")
- ORDER, HOLY
order of their atomic weights, those having consecutive See also:numbers frequently either belong to the same See also:group or occupy similar positions in different See also:groups, and he pointed out that each eighth See also:element starting from a given one is in this arrangement a See also:kind of re-See also:petition of the first, like the eighth See also:note of an See also:octave in See also:music. The See also:Law of Octaves thus enunciated was at first ignored or treated with ridicule as a fantastic notion unworthy of serious See also:consideration, but the See also:idea, subsequently elaborated by D. I. Mendeleeff and other workers into the Periodic Law, has taken its See also:place as one of the most important generalizations in See also:modern chemical theory. Newlands, who was of See also:Italian extraction on his See also:mother's See also:side, and fought as a volunteer in the cause of Italian freedom under See also:Garibaldi in 186o, died in See also:London on the 29th of See also:July 1898. He collected his various papers on the atomicity of the elements in a little See also:volume on the See also:Discovery of the Periodic Law published in London in 1884.
