3. Nuclear Chemistry

9. Alpha Particles A helium nucleus Contains: 2 protons 2 neutrons Notation: He 4 2

11. Alpha Particles Move at about 1/10 th the speed of light. Can be stopped by: aluminum foil sheet of paper skin

13. Beta Particles A fast moving electron (negatively charged particle) formed by decomposition of a neutron. Notation: e 0 1 0 n 0 e 1 1 p +

15. Beta Particles Move at near the speed of light. Penetrate about 100 times greater than alpha particles Can be stopped by: aluminum shield hand

17. Gamma Ray They are high-energy electromagnetic waves NO mass NO electrical charge Notation:  0 0

18. Gamma Ray The most penetrating of all the particles. Can be stopped by: Lead shield Concrete
