Could you please explain this problem for me.
How many of the following elements can form compounds with an expanded octet?
I, O, Cl, Xe
Xe, Xe has a full octet of electrons. when it is involved in the formation of a compound, it has to expand the room available to bond to another element and accept the ‘extra’ electrons from that element
in ClF3, Cl expands its ‘octet’ to accomodate 2 extra F atoms.
F – Cl – F
the F atoms fulfill the octet rule but Cl now has 10 electrons
I can expand its octet when forming I3-
I – I – I
the 2 end I atoms have full octets while the central I atom has 10 electrons.
