When Mendeleev proposed his periodic table, the noble gases had not been discovered, so they did not play a part in his development of the periodic table.

Dmitri Mendeleev did not discover the noble gases as they were not known at the time he created the Periodic Table. The noble gases were discovered later by other scientists. Mendeleev's periodic table focused on arranging elements by Atomic Mass and properties to show periodic trends.

What elements did Dmitri mendeleev discover?

In 1869, a total of 63 elements had been discovered by. A few were gases. Two were liquids. Most were solid metals.


Why did Mendeleev's periodic table not contain the noble gases?

Because noble gases were not discovered when Mendeleev formulated his periodic table


What family are the noble gases in?

Noble gases are in the group 18 of the periodic table of Mendeleev.


Why couldn't Mendeleev predict the existence of the noble gases in the periodic table of elements?

Mendeleev couldn't predict the existence of noble gases because they are inert and do not readily form compounds with other elements. Mendeleev's periodic table was based on the properties of elements and their compounds, and since noble gases do not readily form compounds, they did not fit into his classification scheme.


What group do noble gases belong to?

Noble gases are placed in the group 18 of the periodic table of Mendeleev.


Mendeleev's periodic table did not include the group we now know as noble gases What might be the reason?

During Mendeleev's time, noble gases were not discovered yet. They were later discovered in the late 19th and early 20th century, after Mendeleev had created his periodic table.


Periodic table what was missing at first?

When the periodic table was first created by Dmitri Mendeleev in 1869, there were some gaps or missing elements that had not yet been discovered. Mendeleev left spaces in his table for these unknown elements, accurately predicting both their properties and where they would be located in the table once they were discovered. Over time, these missing elements, such as gallium and germanium, were discovered and filled in the gaps as Mendeleev had predicted.


Why did the periodic table not include the noble gases?

The noble gases were not included in the original periodic table because they were not discovered until the late 19th century. Once they were discovered, they were added to the periodic table as a separate group due to their unique chemical properties and lack of reactivity with other elements.


Which groups of elements contains only noble gases?

This is the group 18 of the periodic table of Mendeleev.


What was the most important step in the development of the periodic table?

The most important step in the development of the periodic table was Dmitri Mendeleev's organization of elements by atomic mass and properties, leading to the creation of the first periodic table in 1869. This laid the foundation for understanding the periodic trends and predicting the properties of undiscovered elements.


What was Joseph priestley contribution to the periodic table?

Joseph Priestley did not contribute directly to the periodic table. He is known for his discovery of oxygen and several other gases, as well as his work on the chemistry of combustion and respiration. The periodic table was developed by Dmitri Mendeleev in 1869 based on the properties of known elements at the time.


What complete family of chemical did mendeleev leave out of his periodic table?

Mendeleev left out the noble gases (Group 18) from his periodic table because they were not discovered yet at the time he developed the table. These elements were later added to the periodic table as they were discovered.
