WebJun 14, 2014 · While progressing down Group 2, the size of the cation increases since the number of shells increases to accommodate to the extra electrons. Due to this, the distance between the centres of mass of the cation and the anion increases and by definition, the lattice enthalpy decreases. WebGroup 2 hydroxides:— Mg (OH)2 Ca (OH)2 Sr (OH)2 Ba (OH)2 *They are all ionic solids But, from Mg2+ to Ba2+, cationic size obviously increases. Bigger cation has less polarizing power.hence Mg (OH)2 having smaller Mg2+ cation,exhibit more polarizations which result in COVALENCY and weakest lattice!
