Is there a pattern or way to know which elements have exceptions to the octet rule or is it just best to memorize them? Also what are the different types of exceptions? (ex. Expanded etc.)

generally elements of period 3 do not obey the octet rule. There are a few elements that are not in period 3 that also come under these exceptions, you should memorise them.
