Bohr Angular Momentum Calculator

Formula

The formula to calculate the angular momentum from Bohr's model is:

$\text{L} = \frac{n \times H}{2 \pi}$

Where:

$\text{L}$ is the angular momentum from Bohr's formula
$\text{n}$ is the principal quantum number
$\text{H}$ is Planck's constant ( $6.626 \times 10^{-34} \, \text{m}^2 \cdot \text{kg/s}$ )

What is Angular Momentum from Bohr's Model?

Angular momentum from Bohr's model refers to the quantized angular momentum of an electron in a hydrogen atom. According to Bohr's theory, the angular momentum is quantized and can only take on discrete values, which are integral multiples of $\frac{h}{2\pi}$ , where $h$ is Planck's constant.

Example Calculation 1

Let's assume the following value:

Principal Quantum Number (n) = 1

Using the formula:

$\text{L} = \frac{1 \times 6.626 \times 10^{-34}}{2 \pi} \approx 1.054 \times 10^{-34} \, \text{m}^2 \cdot \text{kg/s}$

The Angular Momentum is approximately $1.054 \times 10^{-34} \, \text{m}^2 \cdot \text{kg/s}$ .

Example Calculation 2

Let's assume the following value:

Principal Quantum Number (n) = 2

Using the formula:

$\text{L} = \frac{2 \times 6.626 \times 10^{-34}}{2 \pi} \approx 2.108 \times 10^{-34} \, \text{m}^2 \cdot \text{kg/s}$

The Angular Momentum is approximately $2.108 \times 10^{-34} \, \text{m}^2 \cdot \text{kg/s}$ .
