☯ Stable electron configuration
- It's valence shell is complete.
- It has 2 electrons in it's valence shell
- It does not gain, loose or share electrons.
- Ex: Helium (He)
☯ Unstable electron configuration
- It's valence shell is incomplete
- It tends to attain stable electron configuration of the nearest noble gas by sharing electrons.
- Ex: Hydrogen (H)
☯ Valence shell is the outermost shell of an atom of element.
