Question

A single electron orbits a stationary nucleus of charge +Ze, where Z is a constant and e is the magnitude of the electronic charge. It requires 47.2 eV to excite the electron from the second Bohr orbit to third Bohr orbit. Find the value of Z.

Answer:

5

Solution:

$13.6 Z^{2} (\frac{1}{2 ^{2}} - \frac{1}{3 ^{2}}) = 47.2$

$Z^{2} = 25$ , so Z = 5

Answer 5
