  1. 3. The ability of an atom to release energy and mass, a process which is known as radiation
  2. 5. The number of protons in an element
  3. 7. The center of an atom, made up of protons and neutrons
  4. 8. number The total number of protons and neutrons in an atom
  5. 12. The amount of time it takes for half of a radioactive substance to decay
  6. 13. Atoms of the same element with different numbers of neutrons
  7. 14. A subatomic particle that has a positive charge, it is also found in the nucleus
Down
  1. 1. A series of decay reactions that are caused by the unstable atom of the previous element
  2. 2. A negatively charged particle, or electron, that is released from an atom when an atom decays
  3. 4. radiation A highly dangerous type of radioactive decay, it has no mass and the isotope doesn't change when it is released
  4. 6. It is also known as radioactive decay, it involves the nucleus of a larger, unstable atom splits into smaller ones and releases neutrons
  5. 9. particle A type of decay particle, it is the least dangerous and the particle is Helium
  6. 10. The nuclei of two atoms fuse, forming a larger atom, and this reaction causes high amounts of energy released
  7. 11. A subatomic particle, it has no charge and is found in the nucleus
