GraphicsMagick is an old fork of ImageMagick that has active development and much less bloat / dependencies.

If you have a ground state hydrogen atom, the the first excitation energy is the distance to the lowest unoccupied orbital i.e. it is the lowest energy that can excite an electronic transition.

The ground state is with the electron in the $1s$ orbital, and the next lowest energy orbital is the $2s$. So the first excitation energy corresponds to the transition $1s^1 \rightarrow 2s^1$. This is the first line in the Lyman series, with a wavelength of 121.57nm. If you calculate the corresponding energy you get 10.2eV.
