| Energy level | $K$ | $L$ | $M$ | $N$ |
| $n=1$ | $n=2$ | $n=3$ | $n=4.....n=\infty$ | |
| Energy | $- 864 \,a.u.$ | Zero |
the excitation energy needed to raise the electron from $M$ level to $n = \infty$ would be :
From above data what is the molecular mass of $CH_4$ containing all isotopes of carbon but hydrogen on ${}_1^1 H$ ................ $\mathrm{u}$ (Given that atomic mass of hydrogen $= 1.008$)
