The reason that Mendeleev didn't make any predictions about the gases was that these gases were not even discovered yet, therefore it was impossible for Mendeleev to make predictions.
----
Dmitri Mendeleev made his predictions on what would fill the gaps on his far from perfect Periodic Table. He predicted their sizes, weights, appearances, etc.
I think the reason he didn't make predictions is because noble gases are not visible, and weightless.
-------------------------------
Mendeleev couldn't predict the noble gases' properties because their existence wasn't known, as implied above.
Argon, a noble gas, was noticed twenty-five years later by John William Strutt and Sir William Ramsey (the names are not really important).
It doesn't matter that the elements weren't discovered. That's the whole point of arranging the elements. To PREDICT the properties of the missing/unknown ones.
What else can I help you with?
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 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.
Why did Mendeleev's periodic table not contain the noble gases?
Because noble gases were not discovered when Mendeleev formulated his periodic table
How did Dmitri Mendeleev discover the periodic table with noble gases?
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 family are the noble gases in?
Noble gases are in the group 18 of the periodic table of Mendeleev.
Why was mendeleev unable to inculde the elements of helium and neon or argon in his tabble?
Mendeleev was unable to include helium, neon, and argon in his table because they were discovered after his periodic table was published in 1869. These noble gases were isolated much later in the late 19th and early 20th centuries and did not fit into Mendeleev's original classification of elements based on their properties.
Was Mendeleev unable to foresee future discoveries based on the elements?
Mendeleev's periodic table successfully predicted the properties and existence of undiscovered elements, such as gallium and germanium. However, he was unable to foresee all future discoveries, as he left gaps for unknown elements that were later filled in by the discovery of noble gases like helium, neon, and argon.
What group of elements did Mendeleev omit?
i have no idea but i will check and keep you posted.
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.
Which groups of elements contains only noble gases?
This is the group 18 of the periodic table of Mendeleev.
Name three sets of elements added to the periodic table after mendeleev's time?
Mendeleev predicted three elements namely Eka- aluminum (which turned out to be Gallium), Eka- boron (which turned out to be Scandium) and Eka- silicon (which turned out to be Germanium). Though these three elements are very famous, Mendeleev also predicted Eka- manganese (which turned out to be Technetium).
Why was mendeleev better than john newlands?
mendeleev was better than john newlands because he gave all the elements systematical manner . he showed 80 elements except the noble gas and inert gas but newlands gave this but in improper manner because of this mendeleev was better
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.
Why did Mendeleev's periodic table not contain the noble gases?
Because noble gases were not discovered when Mendeleev formulated his periodic table
What proved that Mendeleev was right?
The validity of the periodic table of elements, which was originally devised by Mendeleev, has been confirmed by a vast body of chemical research. It would not be an exaggeration to say that everything in the science of chemistry conforms to Mendeleev's theory.
How did Dmitri Mendeleev discover the periodic table with noble gases?
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 family are the noble gases in?
Noble gases are in the group 18 of the periodic table of Mendeleev.
