The general outer electronic configuration of d-block elements is:
And¹⁻¹⁰ (n+1)s¹⁻²
B(n−1)d⁰ ns²
C(n−1)d¹⁻¹⁰ ns¹⁻²
Dns¹⁻² np¹⁻⁶
Answer & Solution
Correct answer: C. (n−1)d¹⁻¹⁰ ns¹⁻²
**(n−1)d¹⁻¹⁰ ns¹⁻²** (except Pd, 4d¹⁰5s⁰). The penultimate d orbital is progressively filled across each row; ns has 1–2 electrons.
