Question

Why did Mendeelev leave a few gaps in his periodic table ?

Answer 1

Reason why Mendeelev leave a few gaps in his periodic table:

• The element arrangements are based on grouping similar elements in the periodic table of Mendeelev.
• At the time of creating the periodic table, some of the elements was not discovered.
• The spaces left in the periodic table is to fill it with elements that has not discovered but must be positioned there after discovery.
• Mendeleev thought in this way and left gaps in between.
