Question

The general electronic configuration of d-block elements is ______.

Options

• (n − 1) d¹⁻¹⁰ns¹⁻²

• (n − 1) d¹⁰ns¹⁻²

• (n − 1) d¹⁰ns²⁻³

• (n − 1) d⁰ns¹⁻²

Answer 1

The general electronic configuration of d-block elements is (n − 1) d¹⁻¹⁰ns¹⁻².

Explanation:

In d-block elements, electrons are populated in the penultimate shell, designated as n − 1. The capacity of the d subshell ranges from 1 to 10. For fully filled and half-filled shells, one electron is extracted from the s subshell.
