Bohr Energy Equation

Bohr Energy Equation

### Formula:

$$E_n=-\frac{2.18\times10^{-18}Z^2}{n^2}J$$

### Terminologies:

- $$E_n$$ → Energy of electron in nth orbit.

- Z → Atomic number.

- n → Principal quantum number.

- J → Joule; SI unit of energy.

### Usage:

- Used to calculate energy of electron in hydrogen-like species.
