Across
  1. 1. particle with a positive charge located in the nucleus of an atom and has a mass of 1 amu
  2. 5. the central part of the atom housing the protons and neutrons.
  3. 7. the number of protons in an atomic nucleus
  4. 8. the particles or the energy that is released from the nucleus.
  5. 9. the process in which an unstable nucleus changes by emitting particles or releasing energy.
  6. 10. these particles consist of helium nuclei, which are 2 protons and 2 neutrons, and are very large.
Down
  1. 2. these particles consist of fast moving electrons (e-), which are much smaller and lighter than alpha particles
  2. 3. a subatomic particle with a neutral charge located in the nucleus of an atom and has a mass of 1 amu
  3. 4. a subatomic particle with a negative charge located orbiting around the nucleus within the electron cloud
  4. 6. this radiation is an extremely energetic form of light, which means it does not have a charge and is not made of matter
