Most Upvoted Answer
With reference to Mendeléev’s Periodic Table, consider the following ...
  • Mendeleev examined the relationship between the atomic masses of the elements and their physical and chemical properties. He observed that most of the elements got a place in a Periodic Table and were arranged in the order of their increasing atomic masses.
  • It was also observed that there occurs a periodic recurrence of elements with similar physical and chemical properties. Mendeléev left some gaps in his Periodic Table. Instead of looking upon these gaps as defects, Mendeléev boldly predicted the existence of some elements that had not been discovered at that time.
