The nucleus of an atom has a radius of about 7.9Ã-10-15 m. The electron is normally at a distance of about 3.4Ã-10-11 m from the nucleus. Assuming the atom is a sphere with a radius of 3.4Ã-10-11 m, find the volume of the atom, Find the volume of the nucleus, and Find the percentage of the volume of the atom that is occupied by the nucleus.
