Question 457: Atoms & Nuclei

Question

Energy of electron in the second orbit of hydrogen atom is $$\mathrm{E}$$. The energy of electron '$$\mathrm{E}_3$$' in the third orbit of helium $$(\mathrm{He})$$ atom will be

Accepted Answer

$$\begin{aligned}
& E \propto\frac{1}{n^2} \
& 	herefore \frac{E_3}{E_2}=\frac{4}{9} \quad 	herefore E_3=\frac{4}{9} E_2
\end{aligned}$$

Answer

$$\mathrm{E}_3=\frac{4 \mathrm{E}}{9}$$

Answer

$$\mathrm{E}_3=\frac{16 \mathrm{E}}{3}$$

Answer

$$\mathrm{E}_3=\frac{16 \mathrm{E}}{9}$$

Answer

$$\mathrm{E}_3=\frac{4 \mathrm{E}}{3}$$
