Expert Solution & Answer

Answer to Problem 1CE

The elements are arranged according to increasing atomic number in a periodic table.

Explanation of Solution

According to Moseley, it was better to define elements on the basis of nuclear charge rather than atomic mass. As due to nuclear charge, a more regular pattern in the properties was observed. The elements are therefore arranged according to atomic number in the modern periodic table. The modern periodic law states that, “ properties of elements recur in a repeating pattern when arranged according to increasing atomic number.”

Conclusion

According to modern periodic law, elements are categorized on the basis of atomic number.
