The nucleus of an atom has a radius of about 6.8×10-15 m. The electron is normally at a distance of about 1.3×10-11 m from the nucleus. Assuming the atom is a sphere with a radius of 1.3×10-11 m,
1. find the volume of the atom.
2. Find the volume of the nucleus.
3. Find the percentage of the volume of the atom that is occupied by the nucleus
