Assertion : According to Mendeleev, the properties of elements are
the periodic function of their atomic masses. Reason: Atomic number is
equal to the number of protons.
Both assertion (A) and reason (R) are true and reason (R) is the correctexplanation of assertion (A).

Answer:
Both assertion (A) and reason (R) are true but reason (R) is not the correctexplanation of assertion (A).
Explanation:
According to Mendeleev, physical and chemical properties of elements are periodic function of their atomic weights (atomic masses).
Atomic number is equal to the number of protons. It is also equal to the number of electrons present in the neutral atom.

Assertion is incorrect but Reason is correct.
that feature had said that both are correct hey
ask to your chemistry teacher he or she they will slap you
that is wrong this one is correct you can ask with your teacher so please vote and like
