The way I interpreted the question is working at an atomic
level, so the sucrose and phosphor reactions are not directly
comparable to H and F, because they involve more atoms.
On a per-atom basis, I think Doug's flourine and lithium
reaction might be the best. On a per-mass basis, I think
atomic flourine and atomic hydrogen tops them all. Robert
I admit I need to study those excel files you sent me regarding
bond energies, etc. {8^D spike
