2. the shell or orbital in which the electron is located relative to the atom's nucleus
4. a kind of radiation including visible light, radio waves, gamma rays, and X-rays
8. a positively charged ion, i.e. one that would be attracted to the cathode in electrolysis.
9. a negatively charged ion, i.e. one that would be attracted to the anode in electrolysis.
11. an energy level defined by quantum theory
14. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
15. diagrams that represent the valence electrons of atoms within a molecule
18. a single electron or one of two or more electrons in the outer shell of an atom that is responsible for the chemical properties
19. The emission of energy as electromagnetic waves or as moving subatomic particles
20. a particle representing a quantum of light or other electromagnetic radiation
21. penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei
22. the tendency of atoms to prefer to have eight electrons in the valence shell

1. equivalent to electrons but arise from radioactive decay of unstable atoms
3. the arrangement of electrons in orbitals around an atomic nucleus
5. A helium nucleus emitted by some radioactive substances
6. the lowest energy state of an atom or other particle.
7. The emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei.
10. a discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents.
12. consists of all the radiations emitted by atoms or molecules
13. the rate at which something occurs or is repeated over a particular period of time
16. the reactants and products in radioactive decay, nuclear fission, or nuclear fusion
17. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
