Question

Write any six main differences between d an f-block elements.

Answer 1

difference between d and f-block element.

	d-block Elements	f-block elements
1.	d-blocks elements are available in nature.	f-block elements are very rare.
2.	These elements exhibit variable oxidation state.	These elements also exhibit variable oxidation state.
3.	Two shells n and (n - 1) are in complete	Three shells n(n - 1) and (n - 2) are incomplete.
4.	Last electron enters the d-orbital of penultimate shell.	Last electron enters the orbital of antipenultimate (n - 2) shell.
5.	d-blocks elements are normally called transitional elements.	f-block elements are normally called inter transitional elements.
6.	These elements are stable.	These elements are less stable and many are rad active elements.
