Answer» the three laminations are: Position of HYDROGEN => Position of hydrogen in the perodic table is Uncertain , Because hydrogen is placed in 1 A group with Alkali metals . Position of isotopes => isotopes haven't been GIVEN separate place in perodic table .Cause of periodicity => MENDELEEV could not explain the cause of periodicity . Separation of SIMILAR elements => some dissimilar elements have been placed TOGETHER . |
