Steps to convert a molecular formula into a Lewis structure

molecular formula

atom placement

sum of valence e-

remaining valence e-

Lewis structure

Place the atom with the lowest EN in the center

Add A-group numbers

Draw single bonds and subtract 2e- for each bond

Give each atom 8e-

(2e- for H)
