| Term | Definition |
| anion | A negatively charged ion |
| atomic mass | The mass of an atom expressed in atomic mass units; the weighted average of the masses of all the naturally occurring isotopes of an element. |
| atomic number | The unique number of protons found in every atom of a particular element. |
| Bohr model | The atomic model developed by Niels Bohr in which electrons travel in distinct spherical regions called energy levels at fixed distances from the nucleus. |
| cation | A positively charged ion |
| electron | The smallest of the main subatomic particles, located outside the nucleus, having a negative charge and a mass that is 1/1836th that of a proton. |
| energy level | In the Bohn model of the atom, the regions located at fixed distances from the nucleus of an atom in which electrons are found. |
| ion | A charged atom or group of atoms that has gained or lost electrons, producing an unequal number of protons and electrons. |
| isotope | An atom of an element that has a different number of neutrons compared with other atoms of that element, resulting in a different mass number. |
| law of electrostatic charges | The law that states that opposite electrical charges attract each other, while like charges repel each other. |
| mass number | The total number of particles found in the nucleus of a particular isotope of an element. |
| neutron | A subatomic particle found in the nucleus of most atoms that has no electrical charge and a mass slightly greater than a proton. |
| nuclear model | The atomic model developed by Ernest Rutherford in which an atom is made up of a tiny, dense, positively charged central nucleus surrounded by negatively charged electrons. |
| plum pudding model | The atomic model developed by J.J. Thomson that views atoms as spheres of positively charged material with embedded electrons. |
| proton | A subatomic particle found in the nucleus of an atom and having a positive charge and a mass slightly less than that of a neutron. |
| quantum mechanical model | The currently accepted atomic model in which electrons are found in orbitals that are positioned around a nucleus that contains protons and (usually) neutrons. |
| quantum mechanics | The branch of physics that explores the behavior of matter and energy at the atomic and subatomic level. |
