Question 1641
In the series Sc (Z = 21) to Zn (Z = 30), why is the enthalpy of atomisation of zinc the lowest?
Question 1642
Why does the trend of increasing second ionisation enthalpy sometimes break in the 3d series?
Question 1643
What is the primary reason for the relatively small increase in first ionisation enthalpy across the 3d transition series (Sc to Zn)?
Question 1644
Why do transition elements generally exhibit higher enthalpies of atomisation compared to s-block elements?
Question 1645
What is the electronic configuration of the Ni2+ ion?
