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.
