SUMMARY

The atomic spin of an atom is determined by the spins of its constituent particles: protons, neutrons, and electrons, all of which are classified as fermions with a spin of 1/2. The total spin of an atom results from the quantum mechanical combination of these intrinsic spins. Additionally, the orbital angular momentum of the electrons contributes to the overall atomic spin. Understanding these components is essential for grasping the fundamental properties of matter.

What gives an atom its atomic spin?
 
Physics news on Phys.org
How deeply do you want this question answered? An atom is given its spin by the spin of its constituent particles. Protons and Neutrons are fermions, as are the electrons, all of which have spin 1/2. These constituent particles' spins combine quantum mechanically to give you the atom's total spin.
 
In addition to the intrinsic spin of the constituents, there is also the orbital angular momentum which also adds to the total spin of an atom.
