हिन्दीWhich of the following sets of quantum numbers describes an electron in a \( 3d \) orbital with maximum multiplicity and positive spin?
Correct answer · Option 2
\( n = 3, l = 2, m_l = -2, m_s = +1/2 \)
Explanation
For a \( 3d \) orbital, the principal quantum number \( n = 3 \) and azimuthal quantum number \( l = 2 \). The magnetic quantum number \( m_l \) can be -2, -1, 0, +1, +2, and spin \( m_s = +1/2 \).
