NEUTRON EMISSION

1) Occasionally emitted by radioactive decay: - Naturally: absorption of cosmic rays high up in the atmosphere can result in neutron emission - Artificially: James Chadwick alpha particle fired at Beryllium resulted in neutrons emitted from that - Nuclear Fission Reactions: Neutrons released from parent nucleus as it splits 2) Neutron emission causes decrease by 1 in mass no. of nucleus, but no change in atomic no.
