Question
The magnetic quantum number for valency electron of sodium atom isSelect an answerA3B2C1Dzero
Solution
The sodium atom has an atomic number of 11. This means it has 11 electrons in its neutral state. The electron configuration of sodium is 1s² 2s² 2p⁶ 3s¹. The valence electron of sodium is in the 3s orbital.
The magnetic quantum number (ml) describes the energy levels available within a subshell and is dependent on the azimuthal quantum number (l). For an s orbital, the l value is 0.
The magnetic quantum number can have values ranging from -l to +l, including zero. Therefore, for a 3s¹ electron (where l=0), the only possible value for the magnetic quantum number (ml) is zero.
So, the correct answer is D: zero.
