One element that was discovered after the original Periodic Table was developed is gallium. It was identified in 1875 by French chemist Paul Emile Lecoq de Boisbaudran, well after Dmitri Mendeleev created the first periodic table in 1869. Gallium's discovery confirmed the predictions made by Mendeleev regarding the existence of undiscovered elements in his periodic table.
What else can I help you with?
Did mendeleev's original table could accommodate elements that did not even exist?
Yes, Mendeleev's original periodic table had gaps to accommodate elements that were yet to be discovered. He even successfully predicted the properties of some of these missing elements based on his table's structure.
What element in the periodic table might have been discovered in Germany?
Germanium
Was helium included in Mendeleev's original periodic table?
No, he did not know about it. Helium was discovered in spectrographs of the Sun in 1868 and isolated in 1895. Mendeleev's original table skipped from hydrogen (1) to lithium (3).
Why did mendeleev not include germanium in the periodic table?
He could not because it had not yet been discovered when he created the table. However he was able to determine that an element was missing at that location and predict the properties it would have when it was discovered. When germanium was discovered and named, his predictions were found to be very accurate.
How didyour table of elements change each time you added new element?
The answer depends on where you started from. The original table, as published by Mendeleev, had a number of gaps and new elements went towards plugging these gaps. However, after 1947, the new elements discovered were appended to the end of the table.
What element, when discovered, empirically supported Mendeleev's table?
The element gallium, discovered in 1875, empirically supported Mendeleev's periodic table by fitting into the predicted gaps in the table based on its properties.
Did mendeleev's original table could accommodate elements that did not even exist?
Yes, Mendeleev's original periodic table had gaps to accommodate elements that were yet to be discovered. He even successfully predicted the properties of some of these missing elements based on his table's structure.
Who edited the periodic table?
Dimitri Mendeleev did the original in 1869. The last naturally occurring element was Francium, and it allows for the addition of elements that were discovered later.
What element in the periodic table might have been discovered in Germany?
Germanium

No, he did not know about it. Helium was discovered in spectrographs of the Sun in 1868 and isolated in 1895. Mendeleev's original table skipped from hydrogen (1) to lithium (3).
What element was named fro the man who fist discovered the periodic table?
Mendelevium.
What was the most recent element found in the periodic table and when was it discovered?
rubidium 1957

Is there an element symbol R?
nope...at least none that have been discovered yet
What is the element in the periodic table named after the person who discovered nucleus?
It is rutherfordium number 104
How will the modern periodic table be disturbed if isotopes of an element are discovered now?
The periodic table would be disturbed only if isotopes of a new element are discovered, because a periodic table is based on order of atomic number, not atomic mass. If new isotopes of a previously known element were discovered, the atomic mass shown in the periodic table might be changed, but this is very unlikely because the atomic masses shown in a periodic table are based on the naturally occurring distribution of isotopes, and any newly discovered isotopes would probably occur only in very small fractions of the total.
