Across
  1. 4. A positively charged particle, found in the nucleus,and weighs exactly 1 AMU
  2. 6. The nuclei of 2 atoms combine, forming an atom with a heavier nucleus
  3. 10. Holds all of the Protons and neutron
  4. 12. Atoms of the same element that have different number of neutrons
  5. 13. The Ability of an atom to emit mass and energy
  6. 14. The time taken for the radioactive isotope to fall to half its original value
Down
  1. 1. A series of events, each caused by the previous one
  2. 2. Weakest form of decay and least dangerous
  3. 3. The number of protons in the nucleus of an atom, determines its place in the periodic table
  4. 5. Has a neutral charge, found in the nucleus, and weighs exactly 1 AMU
  5. 7. A neutron turns into a proton and a electron is emitted
  6. 8. The total number of protons and neutrons in a nucleus
  7. 9. Most dangerous, no changed particles release only high energy gamma rays
  8. 11. The radioactive nucleus of a large atom is split into 2 or more smaller ones,also releases 2 or 3 neutrons
