Electron dot diagrams

Electron dot diagrams

1. Valence electrons are the ones in the highest occupied principal energy level.

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

2. Show valence electrons.

3. Electron dot diagrams are diagrams in which the valence electrons of an atom are shown as dots distributed around the element’s symbol.
