Answer:

modern periodic table

Answer 2

The incorrect statement is that the modern periodic table is based on atomic masses.

• The modern periodic table is the arranged order of the 118 elements present in our planet.
• This arrangement is made on the basis of the atomic number of the elements.
• The atomic number is completely different from the atomic mass. And, the atomic mass is not related with the arrangement of the modern periodic table.
