The ionization energy of a hypothetical atom is 50 eV. If this atom obey Bohr's atomic model, the en — Atomic Structure Chemistry Question

💡 Solution & Explanation

The ground state energy $E_1$ is $-50$ eV. The energy of the $n^{th}$ orbit is $E_n = \frac{E_1}{n^2}$. For the fifth orbit ($n=5$), $E_5 = \frac{-50}{5^2} = \frac{-50}{25} = -2$ eV. Therefore, correct answer is C.
