Question

The Bohr's energy of a stationary state of the hydrogen atom is given as $E_n=\frac{-2\pi m{e}^4}{n^2{h}^2}$. Putting the values of $m$ and $e$ for $n^{th}$ energy level which is not the correct value?

• A. $E_n=\frac{-21.8\times {10}^{-19}}{n^2}Jato{m}^{-1}$
• B. $E_n=\frac{-13.6}{n^2}eVato{m}^{-1}$
• C. $E_n=\frac{-1312}{n^2}kJmo{l}^{-1}$
• D. $E_n=\frac{-12.8\times {10}^{-19}}{n^2}ergato{m}^{-1}$

Answer 1

Answer: (D)

$E_n=\frac{-12.8\times {10}^{-19}}{n^2}ergato{m}^{-1}$
