Covalent compund rules for structure

  1. dtermein total number of VE

  2. place least electro negatuve atom in middle “least VE” (NEVER HYDROGEN)

  3. connect each atom to middle w/a line

  4. place remaining electrons around outside atoms first, if any remain then move to central atom

  5. make sure everyone is stable, if not then share
