SUMMARY
The discussion clarifies the concept of spin in quantum mechanics, specifically addressing the spin-1/2 quantum number associated with particles like electrons and protons. It confirms that the spin quantum number (s) is indeed 1/2, and the total spin angular momentum is represented as 1/2 ħ for each particle, not √3/2 ħ. The confusion arises from interpreting the total angular momentum versus the z-component of angular momentum, which is correctly identified as 1/2 ħ.
