1.	Identify the incorrect statement :
Answer» Li is the hardest ELEMENT AMONG IA group elements Cs has high melting POINT among IA group elements The hydration capacity of `Ba^(2+)` ion is more than `Mg^(+2)` ion. IIA group elements are harder that IA group elements. Solution :B) Among the IA group elements Li has ligh melting point C) Hydration capacity is more for `Mg^(+2)` ion than `Ba^(+2)` ion, due to its small size
