Across
  1. 2. – Particle made of two protons and two neutrons
  2. 5. – device for measuring radiation
  3. 8. - Atoms of the same element with different mass numbers
  4. 10. – an atom with an unstable nucleus
  5. 11. – a neutron decomposes into a proton and an electron, and the electron leaves the atom
  6. 12. - This number tells us the amount of protons plus neutrons
  7. 13. – splitting an atom into smaller parts
Down
  1. 1. – radiation that occurs naturally in the environment
  2. 3. – the time required for one-half of a sample of a radioisotope to decay
  3. 4. – a ray of energy emitted by an unstable nucleus
  4. 6. – the process of an unstable nucleus emitting charged particles and energy
  5. 7. – two atoms combine to form a larger nucleus
  6. 9. - This number tells us the amount of protons in an atom
  7. 10. – the charged particles and energy emitted from radioisotopes
