Moseley made revisions to the periodic table that resolved some of the problems with mendeleev’s version. which of these was a result of his revisions to the periodic table? a) the revised periodic table could account for the discovery of new elements. b)the revised periodic table could account for variations resulting from isotopes. c)scientists could begin to write new information onto each element. d)scientists could begin to place the table on a single sheet of paper.

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
