Problem

For a hydrogen atom, the average distance of an electron in the

n=1

shell is

r_1 = 0.053\,\text{nm}

, while that in the

n=2

shell is approximately

r_2 = 0.212\,\text{nm}

. Using these distances, what is the approximate ratio of the attractive electrostatic force on an

n=1

electron to that on an

n=2

electron? (a)

4:1

(b)

32:1

(c)

16:1

(d)

8:1
