The nucleus of a gold atom has an electric charge of 1.27x10^-17c. Assume that one of its outermost electrons is at 90pm from the nucleus (1pm=10^-12m).

a: What is the electric force between the nucleus and the electron? Is this force attractive or repulsive?

b: What is the electron’s electric potential at that point?

c: The electron jumps to a distance of about 140 pm from the nucleus. How much work was done on the electron?

A hydrogen atom is made up of a proton of charge +Q = 1.60 x10-19 C and an electron of charge –Q= –1.60 x 10-19 C. The proton may be regarded as a point charge at the center of the atom. The motion of the electron causes its charge to be "smeared out" into a spherical distribution around the proton, so that the electron is equivalent to a charge per unit volume of ρ ( r ) = − Q...
