Text books often show the nucleus of a gold atom to be about 1.5 cm in
diameter, with the nearest electrons about 4 cm from the centre of the nucleus.
In reality, the diameter of the nucleus is about 10-15 m and the diameter of the
atom is about 10-10 m.
If a textbook was drawn to scale, how wide would a page be to correctly
accommodate the artwork?
