The d- and f-Block Elements Class 12 Important Questions

d- BLOCK ELEMENTS The d-block elements are often called ‘Transition elements’ because their position in the periodic table is between the s- and p-block elements. The general electronic configuration is (n–1) d1–10ns0–2. In second and third transition series, there are more irregularities in the electronic configurations as compared to those in first transition series due to electron-electron and nuclear-electron interactions.
