Which of the following is correct formula for general electronic configuration of d-block elements?
Correct answer: A. (n-1)d1-10 ns1-2
- A. (n-1)d1-10 ns1-2
- B. (n-1)d1-5 ns1-2
- C. (n-1)d1-4 ns1-2
- D. (n-1)d1-10 ns2
Explanation
d-block elements have a general electronic configuration of (n-1)d1-10 ns1-2. These elements can find stability in half-filled orbitals and completely filled d-orbitals.

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
