expanded octets

Postby Emely Reyna 1F » Sun May 27, 2018 7:30 pm

Hello!
I was a bit confused on the concept of the expanded octet while drawing lewis structures.
I know that any element with a 3d orbital will have an expanded octet but up to how do I know up to how many electrons it can hold?

I think that you would put all the remaining electrons into the central atom as long as the octets of the surrounding atoms are full.

Yes, with an expanded octet, it is referring to the octet of the central atom!

I'm not completely sure, but I think with the expanded octet it can hold up to as many electrons as the largest orbital of that element. For example, if it had a 3d subshell, since it has a d orbital it should be able to hold up to 10 electrons in the expanded octet.

usually i add bonds from each element to the central element and try and give them each an octet with what remaining electrons i have

In the construction of Lewis models, is the rule for expanded octets as follows: If it is on period (3) of the periodic table or lower, it will be able to handle an expanded octet? *Does this follow for all elements on period (3) of the periodic table?
