The discovery
• Discovered the neutron.
• At this time radiation experiments at that time used helium nuclei,
which are electrically charged and therefore repelled by electrical
forces.
• After chadwicks discovery, neutrons could be mediate a nuclear chain
reaction in which eventually led to the atomic bomb and later to
nuclear power production.

How it all happened… and the effect
• Chadwick smashed alpha particles into beryllium, and allowed the
radiation that was released to hit another target.
• Provided the answer for hidden mass in atoms.
• After Chadwicks work, scientists world wide began bombarded of all
types of materials with neutrons.
