Hello everybody! We are discussing this topic but nobody sures what actually happens when we handle things what parts of atoms we actually touch? Or does magnetic sphere of atom stops our fingers to touch electrons and nucleis? How strong their magnetic shields are?
Thanks in advance if you provide any solid facts.

WE never actuality touch anything, the negative to negative charge of electrons put up a repulsive force that prevents anything from touching anything else.
Except under extreme circumstances (heat or pressure).
