JONES Electron Configuration

Last updated over 1 year ago

The periodic table is that it is sectioned off by orbitals, or region of space in which there is a high probability of finding an electron. There are four orbitals, s, p, d, and f which are found in different energy levels called principle quantum numbers. We use the energy level numbers and orbitals in a “code” called electron configuration which helps us express the location of an electron with high probability. We can actually use the periodic table to write our electron configurations. The first row is energy level 1, the second is energy level 2, and so on. *NOTE: The d and f orbital energy levels do not follow the energy levels by row like s and p, so pay attention to those differences.



Look at the periodic table above, all the orange boxes indicates the principle energy level and the atomic orbital that the outer electrons in that specific element occupies.
