    2. The revised periodic table could account for variations resulting from isotopes.

    Mendeleev did not know about isotopes and he arranged the elements in order of increasing relative atomic mass.

    Henry Gwyn Jeffreys Moseley (1887-1915) proposed that the number of positive nuclear charges (protons) in atom is equal to its atomic number in the periodic table.

    For example, positions of iodine and tellurium were reversed in Mendeleev's table, because of different isotopes, but Moseley solved anomalies like this one.

    The answer is A

    We can eliminate D and C because scientist could have done these things regardless of scientific discovery

    And B because isotopes are not on the periodic table

    We also know that is A because Moseley was responsible for organizing the elements by atomic number and because there were gaps (like it might have skipped for 4 to 6 because 5 hadn't been discovered yet) Scientist knew there would be more elements to discover
