# Problem: a) What is the angular momentum of a hydrogen atom in a 4p state? Give your answer as a multiple of h.b) What is the angular momentum of a hydrogen atom in a 5f state? Give you answer as a multiple of ?.

###### FREE Expert Solution

Orbital angular momentum is expressed as:

$\overline{){\mathbf{L}}{\mathbf{=}}\sqrt{\mathbf{l}\mathbf{\left(}\mathbf{l}\mathbf{+}\mathbf{1}\mathbf{\right)}}{\mathbf{\hslash }}}$

a)

For p orbital, l = 1
