WebThe periodic table was actually developed and by Mendeleev in the early 1800’s. However, it was in fact perfected by Henry Moseley, an English physicist in 1913. By making adjustments to the periodic law, he improved on all the flaws of the Mendeleev table. Let us take a look at this development.
