The nucleus of the hydrogen atom has a radius of about 1.0 ×
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.
