the large gaps
Mendeleev was able to predict the properties of the elements that were not discovered at that time. He left gaps for these elements in his Periodic Table.
Mendeleev realized that some elements had not been discovered.
By 1869, a total of 63 elements had been discovered and reported in the scientific literature. These elements formed the basis for Mendeleev's development of the periodic table.
He realized that some elements had not been discovered.
The holes suggested that there were "missing" elements that hadn't been discovered yet. Mendeleev successfully predicted the basic properties of germanium, which hadn't been discovered at the time, based on the properties he expected an element in that position to have. He called it "eka-silicon" (eka is a Sanskrit word meaning "one", because it was one period "higher" than silicon).When germanium was later discovered and turned out to have properties very similar to what Mendeleev had predicted, it went a long way towards validating Mendeleev's concept.

He used the difference method
Mendeleev left gaps for undiscovered elements. He predicted their properties which were found to be accurate later.
The long dashes on Mendeleev's periodic table represent gaps where elements had not yet been discovered but were predicted to exist based on the periodic pattern of elements. Mendeleev used these gaps to accurately predict the properties of the missing elements, leading to the discovery of new elements.
i have no idea but i will check and keep you posted.
It's probably Mendeleev you're after. He came up with the first version of a Periodic Table of the elements, and used this to predict the properties of elements that hadn't been discovered at that time.
Mendeleev realized that some elements had not been discovered.
Mendeleev predicted the existence and properties of germanium by leaving gaps in his periodic table for elements that had not yet been discovered. He correctly deduced the properties of the missing element based on the pattern of elements around its position in the table. When germanium was discovered, its properties closely matched Mendeleev's predictions, confirming the validity of his periodic table.
True.
Mendeleev was the inventor of the Periodic Table. He organized all the known elements into the periodic table based on atomic number. He was also able to predict the existence of elements that had not yet been discovered based on gaps in the table he created. Based on observations of other elements in the groups he was also able to predict the characteristics of these unknown elements as well. NICE! dude
properties. Mendeleev's periodic table had gaps for elements that had not been discovered yet, but he was able to predict their properties based on the patterns of the elements surrounding the gaps. This led to the discovery of new elements like gallium, germanium, and scandium.
