The angular momentum of the electron in the 4th energy shell in the hydrogen atom is ________.

Explanation

To find the angular momentum of the electron in the 4th energy shell of the hydrogen atom, we can follow these steps:

### Step 1: Understand the formula for angular momentum
The angular momentum (L) of an electron in a hydrogen atom is given by the formula:
\[ L = n \frac{h}{2\pi} \]
where:
- \( n \) is the principal quantum number (energy level),
- \( h \) is Planck's constant.
