Size of an electron

  1. Nov 6, 2009 #1
    If the energy of an eletron is increased, is its size also increased? If not, how can it be that something (energy) can have the size of nothing?

    The electron has "infinitely long hands" to interact. It is very sticky. When they say it is "point-like", thay mean the interaction potential has a simple form like 1/r where there is a maximum at only one point.
