GR0877 Problem 6

PROBLEM STATEMENT: This problem is still being typed.

SOLUTION: (E) The n-th shell can accommodate 2n^2 electrons. The factor 2 is due to the fact that each orbital can have at most two electrons (one spin up and one spin down). Thus, the total number of electrons is 2(1^2 + 2^2) = 2 \cdot 5 = 10.
