Electron dot diagram

Electron dot diagram

1. Electron dot diagrams are diagrams in which the valence electrons of an atom are shown as dots distributed around the elements symbol.

2. show valence electrons

3. valence electrons are the ones in the highest occupied principal energy level

   • use electron configuration to determine number of valence electrons
     • nitrogen 1s2 2s2 2p3 has 5 valence electrons
   • valence electrons are responsible for the chemical properties of elements
