Common mistakes
- Isotopes are not "different elements". Same proton number means same element.
- Beta is not an electron from a shell. It is produced in the nucleus. Alpha is not a helium atom (no electrons).
- Do not decrease Z for beta-minus. Students mix it up with alpha. Gamma does not change the isotope numbers.
- Do not divide the activity by 2 and call that the half-life. Half-life is a time.
