Study Notes

Electron Configuration

Electron configuration simplifies the representation of electron distribution in an atom
Electron configurations are useful for predicting an atom's properties (like reactivity).
Noble gases (group VIII A) have full electron shells, making the outer electron configurations stable.
Elements in the same group have similar electron configurations in their valence shells.
Valence electrons are the outermost electrons and participate in chemical bonding.
The configurations of these elements are:
- He: 1s²
- Ne: 1s², 2s², 2p⁶
- Ar: 1s², 2s², 2p⁶, 3s², 3p⁶
- Kr: 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶
- Xe: 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶
- Rn: 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², 4f¹⁴, 5d¹⁰, 6p⁶
Chlorine (Cl) has the configuration: [Ne] 3s²3p⁵
To determine valence electrons: identify the outermost shell and its corresponding electrons.
