John Alexander Reina Newlands (26 November 1837 – 29 July 1898) was a British chemist who worked concerning the periodicity of elements. [1] Newlands was born in London in England, at West Square in Southwark, the son of a Scottish Presbyterian minister and his Italian wife. [2]
22 lis 2024 · John Newlands (born November 26, 1837, London, England—died July 29, 1898, London) was an English chemist whose “law of octaves” noted a pattern in the atomic structure of elements with similar chemical properties and contributed in a significant way to the development of the periodic law.

He is responsible for arranging the known elements in order of increasing atomic weight, and found that elements with similar properties occurred at regular intervals. He divided the elements into seven groups of eight, in what he later called the 'law of octaves'.
The English chemist John Newlands (1838–1898), hypothesizing that the chemistry of the elements might be related to their masses, arranged the known elements in order of increasing atomic mass and discovered that every seventh element had similar properties (Figure 3.4.1 ). (The noble gases were still unknown.)
7 lut 2021 · British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves.
27 sty 2023 · English chemist John Newlands (1838-1898) ordered the elements in increasing order of atomic mass and noticed that every eighth element exhibited similar properties. He called this relationship the "Law of Octaves ".
