Question 400: Atoms & Nuclei

Question

The ratio of the areas of the electron orbits for the second excited state to the first excited state for the hydrogen atom is

Accepted Answer

$$\begin{array}{ll} 
& r_n \propto n^2 \Rightarrow A_n \propto n^4 	ext { where, } A_n=	ext { area } \
	herefore & \frac{A_3}{A_2}=\left(\frac{3}{2}ight)^4=\frac{81}{16}
\end{array}$$
