Answer 4

And can you imaging that if the discovery of electrons didn't do enough damage that the discovery of protons and neutrons would do it in.

The core concepts were valid. That word change I mention is that ELEMENTS are composed of atoms and ELEMENTS are not infinitely divisible but ultimately consist of individual ATOMS of that element.
