Question

to what extent do the electronic configuration recite stability of oxidation states in the first of the Transition Element
​

Answer 1

Answer:

Answer :

The elements in the first-half of the transition series exhibit many oxidation states with Mn exhibiting a maximum number of oxidation states (+2 to +7). The stability of +2 oxidation state increases with the increase in atomic number. This happens as more electrons are getting filled in the d-orbital.

However, Sc ([Ar] 3d14s2) does not show +2 oxidation state, instead, it loses all the three valence electrons to form Sc3+. The +3 oxidation state of Sc is very stable as it attains stable configuration.

For Mn ([Ar] 3d54s2), +2 oxidation state is very stable because after losing two electrons, it attains stable half-filled structure.

Answer 2

To what extent do the electronic configurations decide the stability or oxidation states in the first series of the transition elements? Illustrate your answer with an example. Answer: The presence of half filled or completely filled d-orbitals imparts stability to a particular element/ion. Pls mark the brainiest.
