Answer 1

The correct answer is John Alexander Newland.

Key Points

In 1887, the Royal Society, London gave the Davy Medal for the ‘discovery of the periodic law of chemical elements’ to John Alexander Newland.
British chemist, John Alexander Reina Newlands specialised in elemental periodicity.
John Newlands was the first to create a table of chemical elements grouped according to their respective atomic weight.
He made his idea of the periodicity of the chemical elements, which he had arranged in order of atomic weight, public in 1864.
In order to make a connection with musical octaves, Newlands named this phenomenon, The Law of Octaves after noticing commonalities between elements whose atomic weights varied by seven.

Additional Information

The first person to arrange chemical elements according to their atomic weights was AEB de Chancourtois, who also created an early version of the periodic table known as the "telluric helix" because tellurium was in the centre.
Russian chemist and inventor Dmitri Ivanovich Mendeleev is best known for conceiving the Periodic Law and developing a preliminary version of the periodic table of elements.
A pioneer in creating the first iterations of the periodic table of chemical elements was the German chemist Julius Lothar Meyer.
