Presentation Transcript

  1. Radioactivity

  2. Subatomic particles

  3. APE MAN • The number of PROTONS in the nucleus for any given element is always the same and this is the ATOMIC NUMBER

  4. Label the diagram

  5. Isotopes • Isotopes are atoms of the same element that have different atomic masses

  6. Isotope practice activity

  7. Radioactivity • The process in which an unstable atomic nucleus emits charged PARTICLES and ENERGY.

  8. RADIOISOTOPE • Any atom containing an UNSTABLE nucleus. • Will spontaneously change into other isotopes over time.

  9. Nuclear Radiation • The charged particles and energy emitted from the NUCLEUS of RADIOISITOPES.

  10. Half-Life • The amount of time necessary for one-half of the radioactive material to decay.

  11. Balloon Half-Life

  12. Half Life
