Numbering is incorrect. It goes 1, 1, 2

1, 2, 3

In question 1.3, the code for gold is given as 6s^24f^145d^9

It should be 6s^24f^{14}5d^9

##Issue

- Question three doesn't clearly specify that you have to assume you have N lithium atoms with some being L6 and some being L7

- Check that in the high temperature limit you get the same result as in Exercise 1.1.
- In the high temperature limit $\beta \rightarrow 0$ and $e^{\beta\hbar\omega} \approx 1 + \beta\hbar\omega$, so $C \rightarrow k_B$ which is the same result as in Exercise 1.1.
