, Bonding Theories
• Lewis structures (1916)
• VSEPR Theory (1958)
• Valence Bond Theory (1927)
• Molecular Orbital Theory (1928)
, Lewis Symbols
• The electrons involved in bonding are called
valence electrons.
• A simple way of showing the valence electrons and
tracking them during bond formation uses Lewis
symbols, or Lewis electron-dot symbols.
• We represent the valence electrons as dots around
the symbol for the element.
