Give the definition of Ionisation Energy and explain how it changes across the Periodic Table of the Elements. [21 a Na and Mg are two successive elements in the periodic table with atomic number 11 and 12, respectively. Give a rational explanation why the second ionisation energy (IE2) for Na is 7298 kJ mol-1 while for Mg it is much lower at 1451 kJ mol! [6n With the aid of balanced equations outline and describe how pure deuterium gas can be obtained from water. [4 n. 18 m Describe three different ways to obtain pure H2(g). क
