Isotopes

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

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.

  radioactive material to decay.
