Across
- 4. The number that is used to find the neutron
- 6. same element same number of protons but different number of neutrons
- 7. where the protons and neutrons are
- 10. occurs when a large nucleus is impacted by a neutron
- 12. the neutral charge in a atom
- 14. the process of which the nuclei of radioactive atoms emit mass and energy
Down
- 1. emits a electron and raises the proton by one and changes into a new element
- 2. 2 protons + 2 neutrons are emitted
- 3. most dangerous type of decay
- 5. occurs when two smaller nuclei collide with a large amount of energy
- 8. a series of events that happen after something triggers it.
- 9. The number of protons and neutrons
- 11. Amount of time it takes for half of a sample to decay
- 13. The positive charge of a atom.
