Atomic mass is not a useful basis to construct the periodic table this is because of the following
1)when elements were arranged in increasing order of their atomic mass, all elements were not properly classified according to their properties.
So at some heavier elements are after lighter elements

2) Also placing isotopes was a problem.
Isotopes of an element have same atomic number but different mass number.
So they could not be given a place in Mendeeleves periodic table, which was based on atomic masses...

HOPE IT HELPS..... :-)
