  • Atoms with the same number of neutrons but a different number of protons
  • Atoms with the same number of electrons but a different number of neutrons
  • Atoms with the same number of protons but a different number of neutrons.
  • Atoms with the same number of protons but a different number of electrons

3. Why are gamma rays weakly ionising?

  • Because they don't tend to penetrate far into materials rather than colliding with atoms.
  • Because they're short wavelength electromagnetic waves.
