What is the Octet Rule of Electron Configuration?
Electron configuration is the arrangement of electrons in each energy level or orbit of an atom.
If the outer shell of an atom is not filled to its maximum level, the atom is still reactive and has a tendency to combine with other elements.
The atom only becomes stable when it is filled to the maximum level it can hold on the outer shell.
The octet rule is a rule of thumb that atoms of main-group elements must have 8 electrons in its valence shell.
The octet rule applies to most atoms with a few exceptions. For more information on valence electrons, please click here >>
