Ionization Energy Calculator

Ionization Energy Formula

The formula to calculate the ionization energy is:

\[ E_i = \sqrt{Z} \times 13.6 \]

Where:

• \( E_i \) is the ionization energy (in electron volts, eV)
• \( Z \) is the atomic number

Calculation Steps

1. Find the square root of the atomic number \( Z \).
2. Multiply the result by 13.6 to get the ionization energy in electron volts (eV).

Example Calculation

For an atom with \( Z = 4 \):
\[ E_i = \sqrt{4} \times 13.6 = 2 \times 13.6 = 27.2 \text{ eV} \]
