What is energy associated with fourth orbit of hydrogen atom?
$\left(R_H=2.18 \times 10^{-18} \mathrm{~J}\right)$
- $-0.436 \times 10^{-18} \mathrm{~J}$
- $-0.545 \times 10^{-18} \mathrm{~J}$
- $-0.242 \times 10^{-18} \mathrm{~J}$
- $-0.136 \times 10^{-18} \mathrm{~J}$
Solution
$\begin{aligned}
E_4 & =-2.18 \times 10^{-18} \frac{(1)^2}{(4)^2} \mathrm{~J} \\
& =-0.136 \times 10^{-18} \mathrm{~J}
\end{aligned}$
(For H atom, $\mathrm{Z}=1$ )
