atomic and ionic radii of third transition series elements are less than expected explain why
Answers
Answer:
Hey mate this is your answer...
Explanation:
The second and third transition series elements have almost similar atomic radii. It is due to lanthanod contraction. It arises due to poor shielding effect of d and f electrons.
Answer:
Lanthanoid contradiction is the cause. It develops as a result of the d and f electrons' ineffective shielding.
Explanation:
To explain:
Why atomic and ionic radii of third transition series elements are less than expected.
The atomic radii of the second and third transition series elements are remarkably comparable. The lanthanod contraction is the cause. It develops as a result of the d and f electrons' ineffective shielding.
Lenthanoid contraction occurs in the third transition series following lanthanum. Any atom in the third transition series will have roughly the same size as the element directly above it in the second transition series as a result of this contraction. As a result, their qualities are comparable.
The atomic radii of the second and third transition elements are remarkably comparable.
