Questions
What were the criteria used by Mendeleev in creating his Periodic Table?
What were the characteristics of the atoms that Mendeleev concentrated upon while creating his periodic table?
Solution 1
Mendeleev used atomic mass of the elements as the unique criteria of the elements. He proposed that the chemical properties of elements are the periodic function of their atomic masses. And thus, he arranged the elements in the increasing order of their atomic masses.
Solution 2
He concentrated on the various compounds formed by the elements with Hydrogen and Oxygen. Among physical properties, he observed the relationship between the atomic masses of various elements
