Which of the following is a false statement-
(A) Sodium oxide is more basic then magnesium oxide.
(B) Beryllium oxide is amphoteric
(C) The thermal stability of beryllium carbonate is more than that of calcium carbonate
(D) Beryllium is amphoteric
(C). The thermal stability of calcium carbonate is more as compared to that of beryllium carbonate. The ionic potential () value of is more than that of . So attracts the oxygen of more and on heating beryllium carbonate losses more easily.
