2. What type of particles are alpha particles? (hint, it's an element)

  • Hydrogen nuclei, 1 proton, 1 neutron
  • Helium nuclei. 2 protons, 2 neutrons
  • Nitrogen nuclei. 6 protons, 6 neutrons
  • Oxygen nuclei. 4 protons, 2 neutrons

3. Why are gamma rays weakly ionising?

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

4. Where do radioactive substance give out radiation from? Is it random or regulated?

  • From the nucleus, it's a random process
  • From the protons, it's a random process
  • From electrons, it's a random process
  • From the nucleus, it's a regulated process

5. If isotopes are radioactive, what does that mean?

  • It means it gives out radioactive decay
  • It means it decays into other elements and gives out radiation
  • It means it grows into new elements
  • It has a half-life
