Question
Why are most of the d-block elements called transition elements?
✓
Answer
- d-block elements have electronic configuration$(n-n) d^{n-10}, n s^{I-2}$. They are all metals.
- In the periodic table, they are placed between the ,s-block and p-block elements, i.e., in the groups between 2 and 13.
- They show characteristic properties which are intermediate between those of the elements of s-block and p-block.
- Hence, they show a transition in the properties from those of the most electropositive .v-block elements and less
- electropositive (or electronegative) p-block elements.
- Therefore, most of the d-block elements are called transition elements.
