How many possible values can the spin quantum number (m s ) for an electron have?

Options

  1. A1
  2. B2
  3. C3
  4. D0

Correct answer

B. 2

Step-by-step solution

The spin quantum number (ms) for an electron can have two possible values: +½ and -½, representing the two spin states of the electron, often denoted as "spin up" (↑) and "spin down" (↓).
