What is ratio of the amount of energy required to remove an electron from hydrogen and `He^(+)`ion ?

Explanation

To find the ratio of the amount of energy required to remove an electron from hydrogen and the He⁺ ion, we will follow these steps:

### Step 1: Understand the formula for energy
The energy of an electron in a hydrogen-like atom can be calculated using the formula:
\[ E = -\frac{13.6 \, Z^2}{n^2} \, \text{eV} \]
where:
