Explain the following question (based on ionisation energy): (a) Why IE_(1) of N is higher than that of O atom ? (b) Why IE_(1) of Mg is higher than that of Al atom? (c ) Why IE_(1) of C is greater than that of B atom whereas IE_(2) is reverse ? (d) In general, IE increases along the period (rarr) . Explain why the IE_(2) of Cr is higher than that of Mn (Manganese)? (e) The IE_(1) and IE_(2) of K are 420 and 3050 kJ mol^(-1) respectively and those of Ca are 560 and 1140 kJ mol^(-1) respectively. Compare their values and comment on the differences. (f) The IE of Li , Be and C are 5.5, 9.3 and 11.3 eV . What would be the case and explain. i. K, Ca,Se , ii. N,O,F iii. K^(o+), Ar,Cl^(ɵ) , iv Fe, Fe^(2+), Fe^(3+) v. C,N,O , vi. Cu,Ag,Au vii. K, Rb, Cs , viii Be, B, C ix. Na, Mg, Al (h) Explain why Fe^(2+) is more easily oxidised to Fe^(3+) than Mn^(2+) to Mn^(3+) . (i) Explain whether IE_(1) of two isotopes of same element would be same or different. (j) What are the factors on which IE of main group elements tends to decrease douwn the group (darr) .
