Question

The energy levels of one‑electron ions are given by the equation

 

The equation given is:

\[ E_n = (-2.18 \, \text{aJ}) \frac{Z^2}{n^2} \]

where \( Z \) is the atomic number, \( n \) is the energy level, and aJ is the abbreviation for the unit attoujoules.

**Ionization energy** is the energy needed to eject an electron from an atom or ion.

Calculate the ionization energy, \( IE \), of the one-electron ion \( \text{Li}^{2+} \). The electron starts in the lowest energy level, \( n \).

\[ IE = \]

---

This explanation helps students understand how to calculate the ionization energy for a specific ion, emphasizing the variable components in the equation.
