Web16 mrt. 2024 · The ionisation enthalpy of Mn is [Ar]₁₈ 3d⁵4s² While we move across a period in periodic table ionisation enthalpy increases But Chromium has more symmetrical electronic configuration which makes it having higher second ionisation enthalpy than Manganese The correct order is Cr > Mn > V > Ti Class 12 Class 7 Class 6 WebMn3+, whereas Fe2+ has 3d6 which readily changes to Fe3+ (3d5) which has stable electronic configuration. (b) Zinc does not have unpaired electrons and larger in size, therefore, has weak metallic bonds. That is why it has least enthalpy of atomisation. (c) Sc3+ is colourless as it does not have unpaired electron and cannot undergo d-d transition, Web7 apr. 2024 · (c) Cr, V, Ti, Sc For the periods, the atomic radius will first decrease and then increase, this is due to the pairing of the electrons in the d-orbitals, Cr < V < Ti < Sc (d) I + , I, I − The atomic radius of the cation will be the smaller compared to … how do you say metric in spanish
