The ground state is $1 s^{2} 2 s^{2}$ $1s^2 2s^2$ , and I believe what you are referring to as the second excited state would be $1 s^{2} 2 p^{2}$ $1s^2 2p^2$

Explanation:

The ground state is $1 s^{2} 2 s^{2}$ $1s^2 2s^2$ , but I'm not clear on the meaning of "second excited state". I will guess that we are talking about raising the energy of one of the $2 s$ $2s$ electrons into a higher energy level.

If so, the first excited state is $1 s^{2} 2 s^{1} 2 p^{1}$ $1s^2 2s^1 2p^1$ , I assume the second one is $1 s^{2} 2 p^{2}$ $1s^2 2p^2$ , as this would require less energy than elevating a valence electron all the way up to $3 s$ $3s$ .
