Question

Compare the stability of oxidation states of 3d series elements with those of 4d and 5d series elements.​

Answer 1

Answer:

CONCLUSION • The 4d elements are larger in size as compared to 3d elements. The 4d and 5d elements exists higher oxidation state than 3d elements. The 3d elements forms paramagnetic complexes whereas 4d and 5d elements forms diamagnetic complexes.

Hint:The D-block total 4 series are present 3d, 4d, 5d and 6d series. The 6d series is incomplete and 3d, 4d and 5d consists of 10 elements each. ... The valence electrons of these elements lie in the d-orbital of the electronic configuration. The first three rows of D-block are referred to as 3d, 4d and 5d series.
