A perspective/scale question: In a hydrogen atom, if the proton was the size of a tennis ball, (say 6.5 cm), on average how far away from the proton would the electron be orbiting?

A hydrogen atom is 1.1 angstroms in diameter, a proton 1.7 x 10-5. so the atom is 64706 times bigger than the proton. That means your scaled up atom would be 4206 meters across, or about 2.1 km from center to "orbit".
