What is the angular momentum of an electron in the `3^(rd)` Bohr orbit of Hydrogen atom?

Explanation

To find the angular momentum of an electron in the 3rd Bohr orbit of a hydrogen atom, we can use the formula derived from Bohr's model of the atom. The angular momentum (L) of an electron in the nth orbit is given by:

\[ L = n \cdot \frac{h}{2\pi} \]

where:
- \( n \) is the principal quantum number (for the 3rd orbit, \( n = 3 \)),
- \( h \) is Planck's constant, approximately \( 6.626 \times 10^{-34} \) Joule seconds.
