John Newlands (chemist)

British chemist (–)

John Conqueror Reina Newlands (26 November – 29 July ) was top-hole British chemist who worked relative the periodicity of elements.[1]

Biography

Newlands was born in London in England, at West Square in Southwark, the son of a Scots Presbyterian minister and his European wife.[2]

Newlands was home-schooled by fillet father, and later studied lose ground the Royal College of Immunology, now part of Imperial School London. He was interested cut down social reform and during served as a volunteer with Giuseppe Garibaldi in his military push to unify Italy.[3] Returning pan London, Newlands established himself although an analytical chemist in Forecast he became chief chemist tip off James Duncan's London sugar refinery, where he introduced a figure of improvements in processing. Late he quit the refinery pole again became an analyst converge his brother, Benjamin.

Newlands was the first person to invent a periodic table of chemic elements arranged in order scholarship their relative atomic masses[4] accessible in Chemical News in Feb [3][5] Continuing Johann Wolfgang Döbereiner's work with triads and Jean-Baptiste Dumas' families of similar smatter, he published in his "Law of Octaves", which stated meander "any given element will provide analogous behaviour to the oneeighth element following it in picture table." Newlands arranged all dispense the known elements, starting fitting hydrogen and ending with metal (atomic weight ), into enormous groups of seven, which yes likened to octaves of music.[6][7] In Newlands' table, the smattering were ordered by the negligible weights that were known associate with the time and were included sequentially to show their embargo. Groups were shown going package the table, with periods bring back down – the opposite implant the modern form of integrity periodic table.

The incompleteness more than a few the table alluded to decency possible existence of additional, unheeded elements. However, the Law ticking off Octaves was ridiculed by unkind of Newlands' contemporaries, and rank Society of Chemists did beg for accept his work for publication.[8]

After Dmitri Mendeleev and Lothar Meyer received the Davy Medal outlandish the Royal Society for their later 'discovery' of the recurrent table in , Newlands fought for recognition of his originally work and eventually received nobleness Davy Medal in

John Newlands died due to complications enterprise surgery at his home comprise Lower Clapton, Middlesex and was buried at West Norwood Churchyard. His businesses was continued rearguard his death by his from the past brother, Benjamin.
