Answer:
Mendeleev’s table of elements was better accepted than those of other scientists at the time because he discovered the elements that had not yet been discovered. Moseley went a step further in suggesting that the elements be arranged according to atomic number
Atomic number
Step-by-step explanation:
He arranged the elements based in groups.
He left spaces for the elements yet to be discovered. His assumptions were true as the elements were actually discovered later on
The properties of such elements were also well matched as based on their position in the periodic table.
He corrected some of the incorrect masses predicted by then.
The modern periodic table is based on periodic trend on atomic number.
