Why did Dmitri mendeleev reverse the order of some elements in the periodic table?

He was bold enough to reverse the order of some pairs of elements and to predict that their atomic masses were incorrect. Some of these predictions were correct, but others were not, because we now know that the fundamental basis of the periodic table is atomic number rather than Atomic Mass.
