Question

What is the potential energy of an electron present in N-shell of the Be+3 ion ?

-3.4 eV

​-6.8eV

-13.6eV

-27.2eV

Please give working for your solution.
Thank you.

Answer 1

The N-Shell of the beryllium does not exist because it has 4 electrons in neutral state and Be3+ has only one electron which is in the K - shell. The beryllium can have its electron in the N-shell in excited state and its potential energy can be calculated by de-broglies wave equation and Einstein equation and its derivation which includes Work Function
