Question

With respect to the merits of the Mendeleev periodic table answer the following question.

Which atomic weights were collected with the help of this periodic table?

Answer 1

1. In Mendeleev, periodic table elements were arranged based on increasing atomic mass. During Mendeleev, only 63 elements were known so after studying the properties of elements he arranged them into vertical columns called groups and horizontal rows are called periods.
2. Mendeleev's periodic table helped in correcting the atomic masses of some of the elements, based on their positions in the periodic table.
3. The atomic weight of the element is calculated based on the product of the equivalent mass of the element and its valency.
4. The atomic mass of Beryllium, Gold, and Platinum was corrected by Mendeleev's periodic table.
