Question

Read the paragraph and answer the following question,
(3)
Energy is always required to remove electron from an atom and hence ionization enthalpies are
always positive. The second ionization enthalpy will be higher than the first ionization enthalpy.
The term ionization enthalpy, if not qualified, is taken as the first ionization enthalpy. The
ionization enthalpies and atomic radii are closely related properties,
a) The first, second and third LE of Al are 577, 1816 and 2744 kJ/mol. What is the amount of
energy required to convert one mole of Al into Alion,
b) The first LE of third period elements Na, Mg and Si are 496,737 and 786 kJ/mol, Predict
whether the first IE value for Al will be more close to 575 or 760kJ/mol, c) LE of Boron is
slightly less than Be. Why?​
