See also:JOHN See also:ALEXANDER REINA See also:NEWLANDS (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
.
See also: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
