  1. 1. A subatomic particle with a positive charge.
  2. 2. The fundamental building block of all matter.
  3. 3. A positively charged particle (a helium nucleus) given off during some types of radioactive decay.
  4. 4. The spontaneous disintegration of certain nuclei accompanied by the emission of alpha, beta or gamma radiation.
  5. 9. A negatively charged particle (an electron) given off during some types of radioactive decay.
  6. 11. A substance that speeds up a chemical reaction.
  7. 12. A subatomic particle with a negative charge.
  8. 13. A substance that cannot be further broken down by chemical reactions.
  9. 14. A charged particle formed when an atom loses or gains electrons.
