1. The problem statement, all variables and given/known data
This question refers to Kittel's Solid-state physics book.

I think it is obvious that we should use equations (51) and (52) here but I am very confused about this problem because Kittel never says what the impurity is and what the impurity is in.
Can someone fill in the blanks:
(a) Calculate the donor ionization energy of _____ in _______ .

2. Relevant equations

3. The attempt at a solution
