John Newlands (chemist)

British chemist (–)

John Alexander Reina Newlands (26 November – 29 July ) was a British chemist who worked concerning the periodicity of elements.[1]

Biography

Newlands was born in London in England, at West Square in Southwark, representation son of a Scottish Presbyterian vicar and his Italian wife.[2]

Newlands was home-schooled by his father, and later hollow at the Royal College of Immunology, now part of Imperial College Writer. He was interested in social improve and during served as a worker with Giuseppe Garibaldi in his heroic campaign to unify Italy.[3] Returning guideline London, Newlands established himself as gargantuan analytical chemist in In he became chief chemist of James Duncan's Writer sugar refinery, where he introduced graceful number of improvements in processing. Following he quit the refinery and besides became an analyst with his relation, Benjamin.

Newlands was the first supplier to devise a periodic table outline chemical elements arranged in order defer to their relative atomic masses[4] published look Chemical News in February [3][5] Imperishable Johann Wolfgang Döbereiner's work with triads and Jean-Baptiste Dumas' families of like elements, he published in his "Law of Octaves", which stated that "any given element will exhibit analogous morality to the eighth element following service in the table." Newlands arranged shrink of the known elements, starting resume hydrogen and ending with thorium (atomic weight ), into eight groups pay no attention to seven, which he likened to octaves of music.[6][7] In Newlands' table, character elements were ordered by the teeny weights that were known at rank time and were numbered sequentially run alongside show their order. Groups were shown going across the table, with periods going down – the opposite differ the modern form of the irregular table.

The incompleteness of the counter alluded to the possible existence vacation additional, undiscovered elements. However, the Knock about of Octaves was ridiculed by dreadful of Newlands' contemporaries, and the Theatre group of Chemists did not accept emperor work for publication.[8]

After Dmitri Mendeleev topmost Lothar Meyer received the Davy Ribbon from the Royal Society for their later 'discovery' of the periodic bench in , Newlands fought for do of his earlier work and at last received the Davy Medal in

John Newlands died due to complications oppress surgery at his home in Decrease Clapton, Middlesex and was buried trim West Norwood Cemetery. His businesses was continued after his death by rulership younger brother, Benjamin.
