Question

For each value of the principal quantum number n, what are the possible values of the electron spin quantum number m_s?

Answer 1

Answer:

d) and e)

Explanation:

• For any value of the principal quantum n, the only possible values of the electron  spin quantum number m_s are + 1/2 and -1/2.
• Since this number is related with the angular momentum of the electron, it has a magnitude (1/2) and an orientation given by the sign (+ or -)
• So, the only right answers are d) and e).
