Question

Mendeleev leave gaps in periodic table

Answer 1

Answer:

Why did Mendeleev left some gaps in his periodic table? To make sure that elements with similar properties lie in the same group, Mendeleev left some gaps in the periodic table. These gaps were left for subsequent inclusion of the elements not known at that time. The elements were discovered later.

Mendeleev left some gaps in his periodic table because he believed that in future more elements will be discovered. He predicted the existence of some elements and named them by prefixing a Sanskrit numeral, Eka (one).
