Lewis Structure and Quantum Mechanics
Key Ideas of Lewis Bonding:
• Atoms and ions are stable if they ahve a noble gas-like
electron structure
• Electrons are most stable when they are paired
• Atoms form chemical bonds to achieve a stable octet
• A stable octet may be achieved by an exchange of
electrons between a metal and a non-metal
• A stable octet of electrons may be achieved by the
sharing of electrons between non-metals
• The sharing of electrons results in a covalent bond
