3. diagrams that represent the valance electrons of atoms within a molecule
7. the orbital in which the electron is located relative to the atom's nucleus
9. energy that moves from one source to another
10. an ion with a positive charge
13. the number of times a value occurs in a set of data
15. a form of energy that grows as electric and magnetic waves traveling in packets of energy
19. the state of lowest energy for that electron
20. the smallest disconnected unit of an event
22. the arrangement of electrons in orbitals around an atomic nucleus

1. When 2 protons and 2 neutrons tightly skip together
2. the pattern of lines formed when light passes through a prism to separate it into the different frequencies of light it contains
4. When substances suddenly release radiation
5. the tendency of atoms to prefer to have eight electrons in the valence shell
6. an electron or positron that is thrown out from the nucleus of an atom during radioactive decay
8. the basic unit that makes up all light
11. When the reactants and products in radioactive decay, or nuclear fission are represented
12. light forms of energy that travel in waves
14. the distance between two consecutive troughs of a wave
