Unformatted text preview: 1 x C, 1 x H, 3 x Cl 2. Write the electron dot notation for each type of atom in the molecule 3. Determine the total number of valence electrons to be combined 4. Arrange the atoms to form a skeleton structure for the molecule. If carbon is present, it is the central atom. Otherwise, the least electronegative element atom is central (except for hydrogen, which is never central). Then connect the atoms by electron-pair bonds. 5. Add unshared pairs of electrons so that each hydrogen atom shares a pair of electrons and each other nonmetals is surrounded by eight electrons. 6. Count the electrons in the structure to be sure that the number of valence electrons used is equal to the number available. Updated: 11/22/2011...
