What is the major difference between the periodic table created by dmitri mendeleev and the one created by henry moseley? moseley arranged the elements in order of increasing atomic mass. moseley ignored variations resulting from isotopes. moseley arranged the elements in order of increasing atomic number. moseley divided the elements into four categories.

The major difference between the periodic table created by Dmitri Mendeleev and the one created by Henry Moseley is that:

Moseley arranged the elements in order of increasing atomic number. 

Mendeleev ordered his components so as of their relative atomic mass, and this gave him some issues. He did exploitation of number rather than mass because the organizing principle was initially projected by the British chemist Henry Moseley in 1913, and it solved anomalies like this one.
