Compare the stability of (+2) oxidation state for the elements of the first transition series. |
|
Answer» Solution :The most common oxidation state of elments in FIRST transition series is (+2). The (+2) oxidation state arises due to participation of 4s ELECTRONS. From Sc to MN, the tendency to SHOW the higher oxidation state increases and then decreases as d-electrons START pairing. Thus in a series, TI(II) is less stable than Ti(IV). Sc(II), however does not exist, while zinc exists only as Zn(II) |
