Electrons in Atoms: Page 6
Steps for Writing the Electron Configuration
S- 2 electrons
P- 6 electrons
D- 10 electrons
F- 14 electrons
Illustration of Electron Configuration
-Symbol: C, e- = 6
Use Aufbau's Principle to start on the energy level 1s and continue to show the amount of electrons you have in the element. You start on 1s and follow the arrows to know which energy level you're on.
1s^2 2s^2 2p^2
Example of an Electron Configuration
Helium only has 2 electrons. Therefore, He only needs to be shown will energy level 1s.
