What is Ionization Energy?

Ionization Energy is the energy required to remove an electron from an atom or ion in its gaseous state. The most common units for Ionization Energy are electron volts (eV).

Example Calculation 1

Let's assume the following value:

Using the formula:

\[ Ei = \sqrt{4} \times 13.6 = 2 \times 13.6 = 27.2 \text{ eV} \]

The Ionization Energy is 27.2 eV.

Example Calculation 2

Let's assume the following value:

Using the formula:

\[ Ei = \sqrt{9} \times 13.6 = 3 \times 13.6 = 40.8 \text{ eV} \]

The Ionization Energy is 40.8 eV.
