Mendeleev left some gaps in his table for the elements which were not discovered at that time.Those elements were later found as silicon,gallium,germanium which were then filled in the gaps

Who organized the very first periodic table?

The first periodic table was organized by Dmitri Mendeleev in 1869. Mendeleev arranged elements according to their atomic weight and properties, leaving gaps for unknown elements that were later discovered.


How many blank spaces did Mendeleev leave in the periodic table which represented elements that had not yet been discovered?

Mendeleev left gaps for eight elements in his periodic table that were yet to be discovered. These gaps eventually corresponded to the elements gallium, germanium, scandium, technetium, francium, and technetium.


Why did mendeleev leave blank spaces on his periodic table?

Mendeleev left blank spaces because certain elements on the Periodic Table were not known at that time. He knew that in the future, those elements would be found and placed on the periodic table.


Why was Mendeleev's decision to leave blank spaces on his table sometime referred to as his most significant contribution to periodic table?

Mendeleev thought about the future and realized that it was entirely unlikely that all earthly elements had been discovered, so he left blank spaces in his table and even predicted some of the elements that would fit in those spaces. Surprisingly enough, as time passed, chemists began discovering many of the elements that he had predicted, which fit perfectly into his periodic table.


What was the problem with the first periodic table?

The first periodic table by Dmitri Mendeleev did not account for the discovery of isotopes (elements with the same number of protons but different number of neutrons) and did not leave spaces for later-discovered elements. Additionally, it did not show the relationship between atomic number and chemical properties.

Why did he leave squares in the first periodic table blank?

I believed you are referring to Dmitri Mendeleev. He left blank space because he was able to deduce a pattern between the chemical properties of the elements an their atomic weights. He also noticed gaps in this pattern and hypothesized correctly that these blank spots corresponded to elements that had not yet been discovered.


Why did Dmitri leave blank spaces on the periodic table?

Dmitri Mendeleev left blank spaces on the periodic table to account for elements that had not been discovered yet. He predicted the existence and properties of these missing elements based on the patterns and trends of the known elements in the table. This allowed for the successful prediction of the characteristics of elements like gallium and germanium.

Why did Dmitri leave blank on the preodic table?

There is no specific reason mentioned for why Dmitri Mendeleev left blank spaces on the periodic table. It is believed that he left these spaces to accommodate elements that were yet to be discovered or to demonstrate the existence of elements with certain properties that were predicted but not yet confirmed. These blank spaces eventually led to the discovery of new elements and validated Mendeleev's periodic table.

How can one make a blank calendars?

One can make a blank calendar using sheets of blank paper! First, draw boxes for the dates and leave them blank. Easy and simple. One can also get paint samples where there are already squares and put them together to form a calendar.

How did Mendeleev know where to leave space in his table?

Mendeleev arranged the elements in order of increasing related Atomic Mass
