Atomic Structure Question 32

Question: Energy of electron of hydrogen atom in second Bohr orbit is

Options:

A) $ -5.44\times {10^{-19}}J $

B) $ -5.44\times {10^{-19}},kJ $

C) $ -5.44\times {10^{-19}},cal $

D) $ -5.44\times {10^{-19}},eV $

Show Answer

Answer:

Correct Answer: A

Solution:

$ E=-\frac{2.172\times {10^{-18}}}{n^{2}}=\frac{-2.172\times {10^{-18}}}{2^{2}} $

$ =-5.42\times {10^{-19}}J $ .
