WebThey used Bohr’s earlier model, which treated the nucleus as a large drop of liquid. In this model, the absorption of a neutron could cause the uranium nucleus to become unstable and divide into two smaller drops. If this division takes place, the resulting drops (nuclear fragments) would be repelled by their respective positive charges. http://www.basic-physics.com/n6-bohr-wheeler-theory-of-fission/
