Limit to expanded octet
Is there a certain amount of lone pairs or bonds that an expanded octet can have?

Re: Limit to expanded octet
It would most likely be limited to the number of electrons available in the element's d-orbital. Typically though, you would use the formal charge of the element to determine how many electrons its expanded octet would typically hold at its lowest energy state.

Re: Limit to expanded octet
Also, so if the expanded octet rule would be limited by the space in the d/f orbitals, would that mean:
-elements in the p-block on period 3 can have an expanded octet of up to... ten electrons..?
-elements in the d-block on period 4 can have an expanded octet of up to 10-how many electrons are in the d-block already. For example, Iron can have an expanded octet of four more electrons (since there's room for four more electrons in the d-block...)
Can anyone confirm? Or at least say their thoughts..?

Re: Limit to expanded octet
Expanded octet often is restrained to those with odd number of valence electrons

Re: Limit to expanded octet
it usually involves the number of valence electrons available in either the d or p block.
Re: Limit to expanded octet
The limit would have to do with number of electrons an entire molecule can have and the formal charges.

The amount of lone pairs or bonds are limited to the amount of un-bonded pairs available in the atom. The number of electrons available in the expanded octet are restricted to the capacity of the d and f orbital.
