Using arguments of quantum mechanics, explain why elements in the same group of theperiodic table exhibit similar chemical reactivity. Choose two or more elements to use as specificexamples in your explanation.

If you were to calculate the distance from the nucleus where maximum probability density occurs (i.e. peaks in the diagram), what would you do? Briefly describe in words. You do not need to solve for the exact numbers.
