But shit nigger, Mendeleev's table actually looked more like this.
See, his periodic law went by atomic mass (weighted average of number of protons + neutrons in isotopes of an element) which is wrong. Current periodic law goes by atomic number which is the number of only protons in an element.
The 11 y/o's on here will be something like "no different hurr you fagit", google isotopes children.

Dmitri Mendeleev only organized the periodic table according to the atomic mass.
He also switched the position of Iodine and Tellerium, mass # 127 and 128 were reversed, 128 then 127.
It wasn't until 1911 and 1913 when in 1913, Henry Moseley managed to actually complete it with periods groups all based on chemical properties..
