In the Angular process as atom makes a transition to a lower state without emitting a photon. The excess energy is transferred to an outer electron which may be ejected by the atom. (this is called an Augar elecrons ) . Assuming the nucleus to be massive , calculate the kinetic energy of an `n=4` Augar electron emitted by chromium by absorbing the energy from a `n=2` to `n=1` transition .

Explanation

To calculate the kinetic energy of an Auger electron emitted by chromium during a transition from \( n=2 \) to \( n=1 \), we will follow these steps:

### Step 1: Identify the Energy Levels
The energy levels of an electron in a hydrogen-like atom can be calculated using the formula:
\[ E_n = -\frac{RZ^2}{n^2} \]
where:
