Maximum electrons in expanded octet
Hi! I'm just wondering what the maximum number of electrons would be in an expanded octet for an element like Iodine?

Re: Maximum electrons in expanded octet
I believe that basically the amount of that the valence shell can hold influences whether or not the element can have an expanded octet. So like with your example of iodine, it can make more than 4 bonds because it has its valence electrons in the 4th energy level, and so then it has access to the empty 4d sublevel, therefore it can have more than 8 electrons in its valence shell.
And I'm not sure what the exact amount is or what the maximum amount is, but Iodine can form 7 bonds, as in IF7.

Uranocene was the the molecule with the highest coordination number I found. It has a coordination number of 16, so it probably has a large number of electrons on the central atom (uranium).

Re: Maximum electrons in expanded octet
Sillicon, sulfur, phosphorus, and chlorine are the most common elements that form an expanded octet, meaning they share more than 8 electrons with other elements in a molecule.
