If you wanted to make an accurate scale model of the hydro- gen atom and decided that the nucleus would have a diameter of 1 mm, what would be the diameter of the entire model?   I understand the answer however wouldnt the end result be much smaller than 106 mm since we are only find the diameter of the nucleus? Is the 106 always used in these types of equations? What would be used in this equation for say a carbon atom?
