$SOLVED:Helium is the lightest noble gas and the second most abundant element (after hydrogen) in the universe. (a) The radius of a helium atom is 3.1 ×10^-11 m ; the radius of its nucleus is 2.5 ×10^-15 m . What fraction of the spherical atomic volume is occupied by the nucleus (V of a sphere =(4)/(3) πr^3) ? (b) The mass of a helium- 4 atom is 6.64648 ×10^-24 g, and each of its two electrons has a mass of 9.10939 ×10^-28 g . What fraction of this atom's mass is contributed by its nucleus?$
