Q. The problem with elements being arranged in the increasing order of atomic masses is that the atomic mass does not increase in a regular manner in going from one element to next. So, it is not possible to predict how many elements could be discovered between the elements. This is why in the Modern Periodic Table elements are arranged according to their ___.
