>>25242903So much wrong in one single post. I can't even.
Using the normally accepted values of .8775 fm (8.775 x 10^-16 m) for the radius of a proton and 53 pm (5.3 * 10^-11 m) for that of a hydrogen atom, it comes out that the atom has a radius ~60,399 times that of the proton. If we divide the radius of earth (6,371 km, or 6,371,000 m) by that figure, we get ~105.482 m (or for you Americans, 346.069 ft). Now, I don't know about you guys, but I've never seen a basketball with a radius of 105.482 m.
Additionally, even assuming your values for the outskirts of the electron cloud are correct (which is doubtful), the sphere you described actually has a radius of 7,959 miles (4,000 plus the 3.959 for the radius of the earth itself.
