For the $\mathrm{d}^{3}$ electron configuration, the ground state term symbol is
(a)${ }^{4} \mathrm{F}_{1 / 2}$
(b)${ }^{4} \mathrm{F}_{3 / 2}$
(c)${ }^{4} \mathrm{F}_{7 / 2}$
(d)${ }^{4} \mathrm{F}_{9 / 2}$
Answer
Answer: B ✓ checked by 4AB · confidence high
Explanation
d³: ⁴F; less than half-filled, so the lowest J = |L − S| = 3 − 3/2 = 3/2 → ⁴F₃/₂.
