The ratio of the energy of the electron in the first excited state of hydrogen to that of the electron in the ground state of $L i^{2 +}$ is :-

Answer:

Solution:

H, $n = 2 : E = - 13.6/4 = - 3.4$ eV. $L i^{2 +}, n = 1 : E = - 13.6 \times 9 = - 122.4$ eV.

Ratio = 3.4 : 122.4 = 1 : 36.

Answer: (B).
