Mass Number A
Beta Particle
High speed Electron
β+ Decay
Proton turns into a neutron and releases a positron
β- Decay
Neutron turns into a proton and an electron is released
Alpha particle
2 neutrons and 2 protons
Gamma
Electromagnet Radiation
Nuclear Fission
Produces two smaller nuclei and releases energy
Uncontrolled chain reactions are used in nuclear weapons
Nuclear Fusion
Joining of two light nuclei into a larger nucleus
Mass is converted into energy in the form of radiation
Nuclear energy
1 a.m.u= 931 MeV
ISOTOPES= Same Z & Different A
ISOBARS= Same A & Different Z
ISOTONES= Different Z and A but same A-Z
