Electron Dot Diagram

Electron Dot Diagram

1. Electron Dot Diagrams give information about where certain electrons are.

2. Here valance electrons in atoms are draw as dots.

3. Examples

   • Lithium = 1s²2s 1 valence electron
   • Beryllium = 1s²2s² 2 valence electrons
   • Nitrogen = 1s²2s²2p3

4. Diagrams of electrons give information about where some electrons are.

5. They can be use to see the reaction when elements react with each other.

6. The valence electrons are responsible of the chemical properties of the elements.

7. The valence electrons are higher in the energy levels.
