unique ideas for elementary student awards do something new and creative this year by awarding your elementary students with unique student awards hopefully one or more of these awards made you think of a specific student
C. Fission: may create radioactive nuclei, may undergo a chain reaction Fusion: energy source for stars Fission and fusion: large amount of energy produced
Unstable (light) nuclei have either too many protons or too. many neutrons to be stable. Neutron-rich Isotopes undergo beta -minus decay; neutron. changes to a proton inside the nucleus and a negatively. charged electron emitted. Proton-rich Isotopes can undergo beta-plus decay; proton. changes to a neutron inside the nucleus and positively. charged antimatter counterpart of electron (positron) emitted. Gamma pairs. After being emitted positron slows down (after travelling. about 1 mm) and interacts with an electron inside patientâs. body.
