Answer:

The correct answer is A.

Explanation:

The periodic table published by Mendeleev in 1869 was the first periodic table to group the elements. Based on the hypothesis that the properties of the elements are a periodic function of their atomic weights, he placed in the table all the elements known up to that moment, which became 63 elements, ordering them in such a way that the elements belonging to the same family appear in the same vertical line. The elements were arranged in the increasing order of their atomic masses.

Have a nice day!
