हिन्दीWhat is the energy associated with the fifth orbit of a hydrogen atom based on Bohr's model, given the first orbit energy is \( -2.18 \times 10^{-18}\text{ J atom}^{-1} \)?
Correct answer · Option 4
\( -8.72 \times 10^{-20}\text{ J} \)
Explanation
Using \( E_n = \frac{-2.18 \times 10^{-18}}{n^2} \), for \( n = 5 \), \( E_5 = \frac{-2.18 \times 10^{-18}}{25} = -8.72 \times 10^{-20}\text{ J} \).
