assertion and reason both are correct and reason is the correct explanation of assertion

Answer 2

Assertion and Reason both are correct and Reason is the correct explanation of Assertion.

- The modern periodic table is based on the atomic numbers of the elements.

- The isotopes of an element have same electronic configuration, i.e., their atomic number is same.

- Hence they are placed at one place at the same position in the modern periodic table.
