Draw the skeletal structure of the compound. 2. Count the total number of valence electrons present; add electrons for negative charges and subtract electrons for positive charges. 3. For each bond in the skeletal structure, subtract two electrons from the total valence electrons. 4. Use the remaining electrons to complete octets of the terminal atoms by placing pairs of electrons on each atom. 5. Place any remaining electrons in pairs on the central atom. 6. If the central atom has fewer than 8 electrons, move one or more pairs from the terminal atoms to form multiple bonds between the central atom and the terminal atoms. • formal charge- used to determine the most plausible Lewis structure • formal charge “equation”- (# of valence electrons for that atom)-(# of bonds to that atom)-(# of dots around that atom)= formal charge • resonance structure- one of two or more equally valid Lewis structures for a single species that cannot be represented accurately with a single Lewis structure • Resonance structures are NOT rapidly changing structure;
