Solution

The correct option is B Mendeleev
Mendeleev arranged the elements first in a regular table known as periodic table according to their molecular masses. The law that the properties of the elements are periodic functions of their atomic numbers.

Also called Mendeleev's law, (originally) the statement that the chemical and physical properties of the elements recur periodically when the elements are arranged in the order of their atomic weights

Hence, the correct option is $B$

Q. Which of the following statement is correct in regard to the classification of elements?

(a) Elements in modern periodic table are arranged on the basis of increasing atomic masses.
(b) Elements in Mendeleev's periodic table are arranged on the basis of increasing atomic numbers.
(c) In modern periodic table, the element nickel of lower atomic mass is kept before the element cobalt of higher atomic mass.
(d) In modern periodic table, the isotopes of chlorine having different atomic masses are kept in the same group.

Q. Assertion :The modern periodic table remove various anomalies of Mendeleev's periodic table. Reason: Modern periodic table was based on the atomic number rather than atomic weight of the elements. The missing elements were given position with their properties in modern table.

Mendeleev predicted the existence of few undiscovered elements based on his periodic table.
