Find the first and second excitation potentials of an atom when its ionisation potential is 122.4 V .

Explanation

To find the first and second excitation potentials of an atom when its ionization potential is given as 122.4 V, we can follow these steps:

### Step 1: Understand Ionization Potential
The ionization potential (IP) is the energy required to remove the most loosely bound electron from an atom. It is given as 122.4 V.

### Step 2: Use the Formula for Ionization Potential
The formula for ionization potential is given by:
\[
