Nuclear Energy

4. weightless packets of energy called photons
6. the release of energy from the decay of the nuclei of certain kinds of atoms and isotopes
8. a subatomic particle with a positive electric charge
10. the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy
11. a series of chemical reactions where the products of the reaction contribute to the reactants of another reaction
13. a type of subatomic particle with no charge
14. a positively charged region at the center of the atom.

1. composite particles consisting of two protons and two neutrons tightly bound together
2. the process by which the nucleus of a heavy atom splits into two lighter elements of roughly equal mass, releasing large amounts of energy
3. a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay.
5. Atoms with the same number of protons but different numbers of neutrons
7. he number of protons in the nucleus of each atom of that element
9. the total number of protons and neutrons in an atom
12. the amount of time it takes for one-half of the radioactive isotope to decay
