1. Three kinds of particle emission
Type of particle
Alpha Particle
Beta Particle
Gamma Particle
Composition
2 protons and 2 neutrons (helium nucleus)
Electron
Electromagnetic radiation
Charge
positive
negative
No charge

2. Which one is most massive among the three radioactive particles?

3. Effects of Electric Field

4. Effects of Magnetic Field

5. Three kinds of particle emission
Type of particle
Alpha Particle
Beta Particle
Gamma Particle
Penetration Power
Paper
Aluminum sheet
Lead

6. Mechanism of Alpha Decay
A helium nucleus is emitted
A-2, Z-4

7. Mechanism of Beta Decay
Electron is emitted
A neutron becomes a proton
Z is unchanged, A+1

8. Mechanism of Gamma Decay
A nucleus gets excited
Due to an energetic collision
Immediately following a radioactive decay
A and Z of the element does not change

9. Nuclear Processes
Fission
Heavy atoms are split and release energy

10. Nuclear Processes Fusion
Lighter atoms combine to make heavier atoms and release energy

11. Nuclear Processes
Mass is conserved.
Energy is conserved.
