Document Summary

Method 1: build from lewis symbols: draw lewis symbols show valence electrons of each atom, pair valence electrons to create a complete lewis structure, group 4,5,6 atoms are usually central , h and group 7 atoms are terminal , make multiple (double, triple) bonds only when necessary, see if there are any charges, if yes, then add/subtract electrons (if no then go to next step, check to see if you reached the noble gas electronic configuration/octet rule for each atom. Method 2: total valence skeleton: determine total number of valence electrons, build skeleton structure (incomplete lewis structure, group 4,5,6 atoms are usually central , h and group 7 atoms are terminal , make multiple (double, triple) bonds only when necessary, see if there are any charges, if yes, then add/subtract electrons (if no then go to next step, check to see if you reached the noble gas electronic configuration/octet rule for each atom.
