General electronic configuration of lanthanides is

Options

(a) (n – 2) f¹⁻¹⁴ (n – 1) s²p⁶d⁰⁻¹ ns²
(b) (n – 2) f¹⁰⁻¹⁴ (n – 1) d⁰⁻¹ ns²
(c) (n – 2)f⁰⁻¹⁴ (n – 1)d¹⁰ ns²
(d) (n – 2) d⁰⁻¹ (n -I) f ¹⁻¹⁴ ns²

Correct Answer:

(n – 2) f¹⁻¹⁴ (n – 1) s²p⁶d⁰⁻¹ ns²

Explanation:

Lanthanides undergo Aufbau’s principle. The principle states that the electrons should be filled in the ground state first, next the excited state will be filled, so have lanthanide comes under F-block elements, Here 14 electrons can be filled from lowest energy levels to highest energy level. The general electronic configuration is (n-2) f⁽¹⁻¹⁴⁾ (n-1) s²p⁶d⁰⁻¹ n s².
