One of the following scientists never made any contribution to the development of the periodic table?
(a) J.J. Thompson
(b) John Newlands
(c) Luther Meyer
The periodic table of elements lists all the elements that exist in the universe. The elements here are arranged by atomic number (number of protons in the nucleus), electron configuration, and chemical properties. The periodic table is cleverly arranged such that specific rows and columns represent a common set of properties for the elements lined up in them. From the periodic table of elements and where the elements are placed, we can reasonably predict which elements make good conductors or which elements are insulators.
Answer and Explanation:
The answer is (a) J.J Thompson. J.J. Thompson made the discovery of the electron but never made contributions to the periodic table itself.
Newlands worked on categorizing the periodicity of the elements through the organization through their atomic masses. Meyer and Mendeleev worked together alongside Robert Bunsen in creating the first working model of what we currently know as the periodic table.
