(d) Potassium iodide 3. benzene Question 23. Why are lithium salts commonly hydrated and those of the other alkali metal ions usually anhydrous? of lime and the product is slaked lime. (b) Lithium The distinctive character of beryllium is mainly due to its small size, high electronegativity and high polarizing power, when compared to other elements in the same block. Answer: (a) iron (d) rubidium (b) Beryllium It is used in the purification of bauxite and petroleum refining. Similarities between beryllium and aluminium: Question 32.
