• The angular momentum of any s orbital is zero, since the wave function for an s orbital has no angular dependence. In other words, recall that angular momentum gives rise to irregular shapes of a given atomic orbital. Well, all s orbitals are spherically symmetric, so angular momentum has no influence on the shape. Consider some of the s orbital wave functions: psi_(1s)(r,theta,phi) = 1/sqrtpi (Z/a_0)^(3//2)e^(-Zr//a_0) psi_(2s)(r,theta,phi) = 1/(4sqrt(2pi)) (Z/a_0)^(3//2)(2 - (Zr)/a_0)e^(-r//2a_0) psi_(3s)(r,theta,phi) = 1/(81sqrt(3pi)) (Z/a_0)^(3//2) (27 - 18 (Zr)/a_0 + 2((Zr)/(a_0))^2)e^(-Zr//3a_0) If you look closely, there is no theta or phi anywhere in these wave functions. As a result, the orbitals they describe are perfect spheres, having zero angular momentum. ## 4. S P D F Orbitals and Angular Momentum Quantum Numbers

• Photons can carry angular momentum, not only due to their spin, but also due to their spatial structure. This extra twist has been used, for example, to drive circular motion of microscopic particles in optical tweezers as well as to create vortices in quantum gases. Here we excite an atomic transition with a vortex laser beam and demonstrate the transfer of optical orbital angular momentum to the valence electron of a single trapped ion. We observe strongly modified selection rules showing that an atom can absorb two quanta of angular momentum from a single photon: one from the spin and another from the spatial structure of the beam. Furthermore, we show that parasitic ac-Stark shifts from off-resonant transitions are suppressed in the dark centre of vortex beams. These results show how light’s spatial structure can determine the characteristics of light–matter interaction and pave the way for its application and observation in other systems. The spatial structure of vortex laser beams associates angular momentum to photons, which, in addition to their spin, can be used to tailor light-matter interactions. Here, the authors excite an atomic transition with a vortex laser beam, showing that the transfer of angular momentum modifies selection rules. ## FAQs

### What is the orbital angular momentum of an S electron? ›

The orbital angular momentum of an electron in any s - atomic orbital is zero.

Why orbital angular momentum of S is zero? ›

The angular momentum of any s orbital is zero, since the wave function for an s orbital has no angular dependence. In other words, recall that angular momentum gives rise to irregular shapes of a given atomic orbital. Well, all s orbitals are spherically symmetric, so angular momentum has no influence on the shape.

Is the total angular momentum of electron in s orbital zero? ›

Total orbital angular momentum of electron in s orbital is equal to zero. An orbital is designated by three quantum numbers while an electron in an atom is designated by four quantum numbers.

What will be the orbital angular momentum of an electron in 2s orbital? ›

For the 2s orbital, the value of l is zero. Hence the value of the orbital angular momentum will be zero.

What is the angular momentum quantum number of an s-orbital? ›

The letter in the orbital name defines the subshell with a specific angular momentum quantum number l = 0 for s orbitals, 1 for p orbitals, 2 for d orbitals.

How do you calculate orbital angular momentum? ›

It was Bohr who put forward The formula for the calculation of the angular momentum of an electron was put forward by Bohr, and according to him, the formula is mvr or nh / 2π . Here, v = the velocity; n = the orbit in which an electron is present; m = mass of the electron ; r is the radius of the nth orbit.

Under what condition angular momentum is zero? ›

If the straight path of the particle passes through the origin, then the angular momentum is zero, which is also a constant.

Why does the s-orbital have the lowest energy? ›

2s (and 3s, 4s, etc.) electrons spend some of their time closer to the nucleus than might be expected. The effect of this is to slightly reduce the energy of electrons in s orbitals. The nearer the nucleus the electrons get, the lower their energy.

What is total angular momentum of a free electron? ›

The total angular momentum is the sum of the spin and orbital angular momenta for the electrons in an atom. In this case, the total angular momentum quantum number is just the spin angular momentum quantum number, ½, since the orbital angular momentum is zero.

What is zero according to the law of conservation of angular momentum? ›

The law of conservation of angular momentum states that, when the net external torque acting on a system is zero, its total angular momentum is conserved and hence, does not change.

### Can a particle have zero angular momentum? ›

In conclusion, a particle whose wavefunction is spherically symetric will have zero angular momentum. Regerdless of its expected value of distance from the center of the system of coordinates.
