2. Lewis Diagrams
Lewis diagrams illustrate chemical bonding by showing only an atom’s valence electrons and the chemical symbol.
Dots representing electrons are placed around the element symbols at the points of the compass (north, east, south, and west).

3. Lewis Diagrams
Lewis diagrams illustrate chemical bonding by showing only an atom’s valence electrons and the chemical symbol.
Dots representing electrons are placed around the element symbols at the points of the compass (north, east, south, and west).
Electron dots are placed singly until the fifth electron is reached then they are paired.
