ELECTRONS OUTSIDE AN ATOM Nagaoka was one of the first to
propose the idea that negatively-charged electrons are located on the outside of the atom.
Also one of the first to propose protons in the nucleus.

RENOUNCING HIS MODEL He abandoned the Saturnian Model in
1908 after there wasn't enough experimental proof to support the model and disprove speculation.
