Passage / Comprehension

Paragraph:The hydrogen-like species $Li^{2 +}$ is in a spherically symmetric state $S_{1}$ with one radial node. Upon absorbing light the ion undergoes transition to a state $S_{2}$ . The state $S_{2}$ has one radial node and its energy is equal to the ground state energy of the hydrogen atom.

Question:Energy of the state $S_{1}$ in units of the hydrogen atom ground state energy is

Options:

Answer:

Solution:

Energy of state, $S_{1} = - 13.6 (\frac{3 ^{2}}{2 ^{2}}) eV /$ atom $= \frac{9}{4}$ of energy of $H$ -atom in ground state $= 2.25$ of energy of $H$ -atom in ground state
