Question

As we move away from the nucleus, the energy of the electron

• A. Increases
• B. Decreases
• C. Remains same
• D. None of these

Answer 1

The correct option is A Increases

Energy of the electron in the $n^{th}$ shell is given by:

$E=-13.6\frac{Z^2}{n^2}eV$

As we move away from the nucleus, n increases and according to the above formula, energy also increases.
