Which of following was not explained by Rutherford?

1. Arrangement of electrons around the nucleus
2. Arrangement of protons
3. Arrangement of nuetrons
4. None of the above

Correct answer: Arrangement of nuetrons

Solution

Rutherford explained the nuclear model of the atom and the general placement of electrons around a central nucleus. Neutrons were not yet discovered in his era, so their arrangement was not explained by him.
