To compare the general characteristics of the first series of transition metals (3d series) with those of the second (4d series) and third (5d series) series metals in the respective vertical columns, we will focus on atomic size as a key factor. ### Step-by-Step Solution: 1. **Understanding Transition Metals**: - Transition metals are elements that have partially filled d-orbitals. The first series includes elements from Scandium (Sc) to Zinc (Zn), the second series includes Yttrium (Y) to Cadmium (Cd), and the third series includes Hafnium (Hf) to Mercury (Hg). 2. **Atomic Size Trend**: ...

The transition element ( with few exceptions ) show a large number of oxidation states . The various oxidation states are related to the electronic configuration of their atoms. The variable oxidation states of a transition metal is due to the involvement of (n-1)d and outer ns electrons . For the first five elements of 3d transition series , the minimum oxidation state is equal to the number of electrons in 4s shell and the maximum oxidation state is equal to the sum of 4s and 3d electrons. The relative stability of various oxidation states of a given element can be explained on the basis of stability of d^(0),d^(5) and d^(10) configuration . In which of the following pairs , the first species is more stable than second one
