Exception to Octet Rule
How do you know when an element can have more than eight electrons? Do we just need to memorize the exceptions or is there some way of figuring it out?

Re: Exception to Octet Rule
The exceptions start in the second row of the p-block, and continue in the rows of the p-block below that.

This is because elements in the 3d row and beyond have n=3 which means L can equal 0,1, and 2 (s,p,d). Elements in the 3rd row actually have access to the d block, allowing them to occupy more electrons, up to 10 more than the octet to be exact. Hope this helps :)

Some common elements that have expanded octets are sulfur, phosphorus, silicon, and chlorine.
