Question 56 Chapter 6 Review The atomic radius of germanium (Z=32) is smaller than the atomic radius of potassium (Z-19) because of O a change in the "n" quantum number. O germanium having 32 rather than 19 electrons. O an increase in the effective nuclear charge. O a decrease in the effective nuclear charge.
