WebIn the series `Sc(Z=21)` to `Zn(Z=30)` the enthalpy of atomisation of zinc is the lowest, i.e., 126 kJ `mol^(-1)`. Why? WebCorrect option is C) Unlike Scandium, Zinc does not have unpaired electrons in the ground state as well as in its common oxidation state. Enthalpy of atomization depends upon …
Web(ii) The enthalpies of atomisation of the transition metals are high. This is due to high effective nuclear charge and large number of valence electrons. This results in formation of strong metallic bonds. (iii) The transition metals generally form coloured compounds. This is due to d-d transition of unpaired electrons. WebThe enthalpy of atomisation of zinc is lowest due to the absence of an unpaired electron, which is responsible for metallic bonding in the elements. Therefore, the inter-atomic …
WebDec 13, 2024 · Therefore, they form very strong metallic bonds which arise due to the presence of unpaired electron in the (n – 1) d subshell resulting in high enthalpy of atomisation. Zn has the lowest enthalpy of atomisation due to the absence of unpaired electrons and weak metallic bonds. WebIn the series Sc (Z = 21) to Zn(Z = 30), the enthalpy of atomisation of zinc is the lowest i.e., 26, kJ mol. Why? The extent of metallic bonding an element undergoes deideds the enthalpy of atomization the more extensive the metallic bonding of an element the more will be its enthalpy of atomization.
