Ionization Energy of Hydrogen-like Species

Ionization Energy of Hydrogen-like Species

### Formula:

$$E_i=\frac{13.6Z^2}{n^2}eV$$

### Terminologies:

- $$E_i$$ → Ionization energy; minimum energy required to remove electron from an atom.

- Z → Atomic number.

- n → Principal quantum number.

- eV → Electron volt; unit of energy.

### Usage:

- Used to calculate ionization energy of hydrogen-like atoms.
