Question:

a. Calculate the mass density of the H atom.

b. Compare your answer with the nuclear density assuming a nuclear radius of 1.0 × 10ˆ’15m.

c. Calculate the mass density of the H atom outside of the nucleus.

Result of 20.13

The answer can be obtained using a numerical problem solver or by successive approximations. Substituting values for r/a0 in

2r 2r a, 1-e 1- 1+ do ao

gives 0.875, 0.898, 0.905, and 0.912 for r/a0 = 2.5, 2.65, 2.7, and 2.75, respectively. 

The radius of the H atom is approximately 2.65a0.
