Electric Field inside a Hydrogen Atom A hydrogen atom is made up of a proton of charge + Q = 1.60 X 10-19 C and an electron of charge - Q = -1.60 X 10-19 C. The proton may be regarded as a point charge at r = 0, the center of the atom. The motion of the electron causes its charge to be €œsmeared out€ into a spherical distribution around the proton, so that the electron is equivalent to a charge per unit volume of

Where a0 = 5.29 X 10-11 m is called the Bohr radius.
