The spin angular momentum for the 's' electron in a H-atom is:
Correct answer: A. (√3/2).ħ
- A. (√3/2).ħ
- B. (1/2).ħ
- C. 0
- D. h
Explanation
The formula for spin angular momentum is √s(s+1.ħ), where s is the spin quantum number. For an electron, s = 1/2. Plugging this into the formula gives √(1/2)(1/2+1..ħ) = √(3/4.ħ) = √3/2.ħ.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
