Confusion on exceptions to the octet rule

Postby Marina Souliman 1K » Thu May 24, 2018 1:16 pm

For the octet expansion exceptions I know it starts with period 3 but does it start with aluminum or does it start with phosphorus? I have conflicting notes from different UA sessions for some reason. Also, if it starts with phosphorus, do aluminum have a different exception? Thank you!

I believe it starts at the beginning of the p group of period 3 with aluminum because silicon can have an expanded octet. In aluminum's case though, while I think it could potentially have an expanded octet, like Boron it can function well with 6 electrons so often has a reduced one.
