Question 38 of 239
Radius of a certain orbit of hydrogen atom is . If energy of electron in this orbit is . then _____
(Given energy of electron in ground state).
Show answer and solution
Answer: 16
We know
$\begin{aligned}
& \mathrm{r}=0.529 \frac{\mathrm{n}^2}{\mathrm{Z}} \Rightarrow 8.48=0.529 \frac{\mathrm{n}^2}{1} \\
& \mathrm{n}^2=16 \Rightarrow \mathrm{n}=4
\end{aligned}$
We know
$\begin{aligned}
& E_{n^{\text {th }}}=\frac{E}{16} \\
& x=16
\end{aligned}$
