  1. Nuclear Equations & Transmutations

  2. Spontaneous Nuclear Reactions: * release of natural radioactivity to become more stable Natural Transmutation: * an element naturally decays to another element

  3. Beta Decay: * Have too many neutrons * Above the band of stability

  4. Beta Decay: Atomic number increases by 1 Number of protons increases by 1 Number of neutrons decreases by 1 Atomic mass remains the same

  5. Beta Decay: * Table N

  6. Positron Decay: * Too many protons  (converts to a neutron) * Below the band of stability

  7. Positron Decay: p  n + e 1 1 0 1 0 1 Atomic number decreases by 1 Number of protons decreases by 1 Number of neutrons increases by 1 Atomic mass remains the same

  8. Alpha Decay: * Nuclei is too heavy * Alpha decay is a transmutation because the atom changes its atomic number and becomes a different element

  9. Alpha Decay: Atomic number decreases by 2 Number of protons decreases by 2 Number of neutrons decreases by 2 Atomic mass decreases by 4

  10. Nuclear Equations: * charge and mass balance It may be annoying, but you know you like it!

  11. Learning Check: Alpha Decay 238 92 U 32 15 P Beta Decay Keep Going, you can do these! Positron Decay 15 7 N

  12. Separation of Radiation:

  13. Artificial Transmutation: * One element is forced to change to another by bombardment with a particle * 2 particles on left side of equation Bombarding particle Target
