Question

Why are transition elements also called d-block elements

Answer 1

1. Transition elements are called d-block elements because their differentiating electrons enter the (n-1)d subshell.
2. These elements are located in the d-block of the periodic table, positioned between the s-block and p-block elements.
3. They show properties transitional between highly electropositive s-block and more electronegative p-block elements.
4. The d-block includes groups 3 to 12 and is characterized by the filling of d orbitals in their electronic configurations.
