The nucleus of the hydrogen atom has a radius of
about 1.1 × 10-15 m. The electron is at a
distance of about 5.29 ×
10-11 m from the nucleus. Assuming the
hydrogen atom is a sphere with a radius of 5.29 ×
10-11 m, find (a) the
volume of the atom, (b) the volume of
the nucleus, and (c) the percentage of
the volume of the atom that is occupied by the nucleus.
