Atoms of different elements also have different sizes, just like kernefs and marbles. Use the atomic radii given below to answer the following questions. Remember that the volume of a sphere is \( \frac{4}{3} \times \pi \times \) radius \( ^{3} \). Please use the precision of the radii in the table to determine the appropriate number of significant figures for the answers. (a) What is the volume of one atom of O? a8 \( \quad \mathrm{A}^{3} \) (b) What is the volume of one atom of Rb? 490 (c) How many \( O \) atoms are needed to occupy the same volume as a Rb atom? (Please add one additional significant figure to the values in parts \( (a) \) and \( (b) \) before calculating the value for part \( (c) \). This is the proper procedure for handina sianificant fiqures and avoiding errors from early rounding.)
