An accurate representation of bonds is an overloaded permenant magnet or electro-magnet.
Imagine an industrial electro-magnet with metal scrap magnetically bonded to it the fisrt layer of
scrap is strongly bonded and acts a conduit of the magnetization the second layer has a lower bond
and the succeding layer exponential less since they are bonding off the proceeding layer.
The atoms not only have to break past the repulsivity of the central or anchor atom but the intially
