Which group of elements could be placed in Mendeleev's Periodic Table without disturbing the original order? Give reason.
Answers (1)
The noble gases could have been placed in a separate group without disturbing the group as they are found in atmosphere with very little concentrations and have inert properties.
When Mendeleev gave periodic table, none of the noble gases were discovered. When they were later discovered, they were placed in a separate group called as Zero group.
