32. Answer ALL parts of this
question. (a) (b) Explain the following observations in first ionisation energies (IE₁). (i) There is a large decrease in IE₁ between He and Li, Ne and Na and, Ar and K. IE₁ is lower for Al than Mg. (ii) (iii) IE₁ is lower than IE2. (6 marks) Explain the trend in effective nuclear charge (Z*) going from left to right across periods in the periodic table and with reference to Z*, rationalise why the ionic radii of the following anions decrease in the order shown: As³-> Se²-> Br.
