Velocity of Electron in nth Orbit

Velocity of Electron in nth Orbit

### Formula:

$$v_n=\frac{2.18\times10^6Z}{n}\ m/s$$

### Terminologies:

- $$v_n$$ → Velocity of electron in nth orbit.

- Z → Atomic number.

- n → Principal quantum number.

- $$m/s$$ → Unit of velocity.

### Usage:

- Used to calculate velocity of electron in hydrogen-like atoms.
