I was actually just learning this. ^-^

C is the right answer because the electrons were discovered 20 years later.

Stephanie Dodson · Answer 2

I believe the correct response would be A. Elements arranged by increasing atomic mass, this was not included in Dmitri's periodic table. Since elements are arranged according to atomic number, the heavier elements are in fact placed in the rows closer to the bottom of the table.
