Question

According to Bohr model of hydrogen, energy is proportional to:-

• A. $\frac{-Z^2}{n}$
• B. $\frac{-n}{Z^2}$
• C. $\frac{-Z^2}{n^2}$
• D. $\frac{-n^2}{Z}$

Answer 1

The correct option is C

$\frac{-Z^2}{n^2}$

From Bohr's model of hydrogen, we have,

$$\begin{gathered} E=-13.6\frac{z^2}{n^2} \\ \Rightarrow E\propto \frac{-z^2}{n^2} \end{gathered}$$

Hence option C is correct.
