(B) Zn , Cd and Hg have low m.p and are comparitively softer than other transition metals. (C) Metallic bond made by elements with d5 configuration is stronger as compared to metalic bond made by elements with dβ configuration. (D) Metals of 5 d series forms strong metallic bonds as compared with metals of 3 d series.
