- 1. Time required for half of a sample to decay
- 3. Most dangerous type of radiation
- 6. Large atom splits into 2 or more smaller atoms and releases 2 or 3 neutrons
- 7. Positive Charge, amount of this is Atomic Number
- 9. A series of events is caused by the previous one
- 10. Contains protons and neutrons, center of an atom
- 12. Weakest type of radioactive decay emits this
- 13. Neutral Charge
- 14. Nuclei of 2 atoms combine
Down
- 2. When the mass is different than what is shown on the periodic table
- 4. The weight of an atom shown on the periodic table
- 5. How elements are organized and identified on the periodic table
- 8. When an atom emits mass and energy, also called radiation
- 11. Negative charge, when neutron turns into proton, this is released
