one of the following scientists never made any contribution to the development of periodic table? (a)j.jthompson (b)John Newlands (c) Luther Meyer (

d) mendeleev

made any contribution? your teacher probably wants answer *a, however, there is no question in my mind that the discovery of the electron led to a great understanding of periodic trends.

j.jthompson

To determine which scientist never made any contribution to the development of the periodic table, we need to look at the contributions of each scientist mentioned.

(a) J.J. Thompson made significant contributions to the development of the atomic theory and the discovery of the electron. However, his work did not directly relate to the formation or development of the periodic table.

(b) John Newlands proposed the Law of Octaves, which was an early attempt to classify elements based on their properties. His work laid the foundation for periodicity but was later superseded by Mendeleev's periodic table.

(c) Luther Meyer was not a significant contributor to the development of the periodic table. He is not widely recognized for any significant contributions related to the subject.

(d) Dmitri Mendeleev is widely regarded as the father of the periodic table. He developed the periodic table based on organizing elements by their atomic mass and properties. His work provided a structure that formed the basis for the modern periodic table.

From the options given, the scientist who never made any contribution to the development of the periodic table is (c) Luther Meyer.
