Answer 2

The basis of the modern periodic table is increasing atomic numbers.

• The properties of elements and their compounds are a periodic function of their atomic numbers, according to the Modern periodic law.

• As a result, elements are arranged in the periodic table in order of increasing atomic number, Z.
