Question
Nuclear fission can be explained based on
- Millikan’s oil drop method
- Liquid drop model
- Shell model
- Bohr’s model
The correct answer is: Liquid drop model
Millikan oil drop method determines the charge on an electron. Liquid drop model explains nuclear fission, Shell model explains the stability of nuclei and Bohr’s model accounts for the stability of the atom and the line spectra of hydrogen atom.
