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? 1.the revised periodic table could account for the discovery of new elements. 2.the revised periodic table could account for variations resulting from isotopes. 3.scientists could begin to write new information onto each element. 4.scientists could begin to place the table on a single sheet of paper.

Answer is: 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.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
