Calculate the energy required for the process ,
` He^+ (g) rarr He^(2+) (g) + e`
The ionization energy for the H-atom in the grounds state is ` 2. 18 xx 10 ^(-18) J "atom"^(-1)`.

Explanation

To calculate the energy required for the process \( \text{He}^+ (g) \rightarrow \text{He}^{2+} (g) + e^- \), we will use the ionization energy formula for hydrogen-like atoms. The formula for the ionization energy \( E \) of a hydrogen-like atom is given by:

\[ E = 13.6 \, \text{eV} \times \frac{Z^2}{n^2} \]

where:
- \( Z \) is the atomic number of the element,
