Question

Total number of statement(s) which is/are correct ?

(i) The electron affinity of phosphorus is more than that of nitrogen.

(ii) Successive ionisation energies for a given atom always increases.

(iii) First ionisation energy of nitrogen is greater than oxygen.

(iv) Order of acidic character : $Cl_{2} O_{7} > SO_{3} > SO_{2} > Al_{2} O_{3}$

(v) Order of acidic strength in water : $HF < HCl < HBr < HI$
