| Atomic number | equals the number of protons in an atom of that element |
| Isostopes | atoms of the same element that have different numbers of neutrons and different mass numbers |
| Energy levels | the possible energies that electrons in an atom can have |
| electron cloud | a visual model of the most likely locations for electrons in an atom |
| Orbital | a region of space around the nucleus where an electron is likely to be found |
| ground state | when all the electrons in an atom have the lowest possible energies |
| electron configuration | the arrangement of electrons in the orbitals of an atom |
