Drawing Lewis Structures The general procedure. .. 1. Sum the valence electrons from all atoms Use the periodic table for reference Add an electron for each indicated negative charge, subtract an electron for each indicated positive charge 2. Write the symbols for the atoms to show which atoms are attached to which, and connect them with a single bond You may need some additional evidence to decide bonding interactions If a central atom has various groups bonded to it, it is usually listed first: CO 3 2- , SF 4 Often atoms are written in the order of their connections: HCN 3. Complete the octets of the atoms bonded to the central atom (H only has two) 4. Place any leftover electrons on the central atom (even if it results in more than an octet) 5. If there are not enough electrons to give the central atom an octet, try multiple bonds (use one or more of the unshared pairs of electrons on the atoms bonded to the central atom to form double or triple bonds) Draw the Lewis structure of phosphorous trichloride (PCl
