# (a) What is the magnitude of the angular momentum for an l = 1 electron? (b) Calculate the magnitude of the electron's spin angular momentum. (c) What is the ratio of these angular momenta?

To determine

(a)

The magnitude of angular momentum for an l=1 electron.

Explanation

Given Data:

Given l=1

Formula Used:

The magnitude of angular momentum is given as

â€ƒâ€ƒL=(l(l+1))(h2Ï€)

Where L= Angular momentum

â€ƒâ€ƒl= Angular momentum quantum

â€ƒâ€ƒh= Planck's constant

Calculation:

Given l=1

Magnitude of angular momentum is calculated as

â€ƒâ€ƒL=(1(1+1))(6

To determine

(b)

The magnitude of the electron's spin angular momentum for l=1 electron

To determine

(c)

The ratio of angular momentum to spin angular momentum
