    4. Radiometric dating is one term

    5. Here's an answer from Yahoo, 4 months ago: Isotopes. When it has a different number of electrons, they're called ions.
    Example: Carbon 12 and Carbon 14 (Used in carbon dating) Carbon 12 has 6 protons and 6 neutrons, while Carbon 14 has 6 protons and 8 neutrons.

    6. a nuclear reaction?

    7. chemotherapy

    This is not my area so be sure to check with your textbook!
