    elements of period 3 and above can expand their valence shells to include extra lone pairs or bonded pairs

    but incomplete octet - in your course or book, do they mean the other exceptions to the octet rule (there aren't enough valence elctrons or there are odd numbers)?

    in any case, you can always count the number of valence electrons and bond pairs and see if anything is different than it should be

    too little = incomplete (many things with Al, Be, B) and "free radicals" to many = expanded (ICl4, phosphorus (PCl5)
