### Angular Momentum

Hi everyone! Can anyone explain to be what an angular momentum value of O means? I am a little unsure of my understanding of angular momentum, so can anyone explain it in simple terms?

Thank you!

### Re: Angular Momentum

Not sure if that is an O or a 0, but a value of 0 would mean that its linear momentum is zero. For an electron for example, that means the electron is stationary. For S orbitals, the angular momentum is 0, because S orbitals are spherically symmetric, and angular momentum is about irregular shapes of an atomic orbital. If you meant "O" the letter, then O can often just mean the origin?

An angular momentum of zero just means that the particle is not moving.

Hi! An angular momentum of 0 means that there is no linear momentum; in other words, the electron is not moving.

### Re: Angular Momentum

yea if the angular momentum is zero then the particle wouldn't be moving at all.

### Re: Angular Momentum

The angular momentum quantum number represents the shape of the orbital that an electron is located in. For an angular momentum of 0, it would mean that the orbital shape would be an s orbital. Angular momentum is associated with rotating motion and if it is equal to zero, it would mean that the particle is not moving.
