"WebIn crystal structures we usually look at cations surrounded by anions, so the radius ratio is defined as Rx/Rz, where Rx is the radius of the cation, and Rz is the radius of the surrounding anions. Since the anions are usually the larger ions, this results in decreasing values of Rx/Rz as the size of the cation decreases. " - Metallic radii of mn

Web(i) Cr and Mn shows maximum number (six) of oxidation states as they have maximum number (five) of unpaired electrons in 3d orbital. (ii) Chromium has the highest m.p as it has maximum number of unpaired electrons and form stronger metallic bonds. (iii) Scandium shows only +3 oxidation state.

WebIn all transition metals (except Zn, electronic configuration: 3 d 10 4 s 2), there are some unpaired electrons that account for their stronger metallic bonding. Due to the absence of these unpaired electrons, the inter-atomic electronic bonding is the weakest in Zn and as a result, it has the least enthalpy of atomization.
