How was Menndeleyev able to predict the existence of elements that had not yet been discovered?

Mendeleev left gaps for undiscovered elements. He predicted their properties which were found to be accurate later.

Was Mendeleev's periodic table accurate enough that he was able to use it to predict the existence and several properties of certain elements that had not yet been discovered?
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.
How did Mendeleev predict the existence of unnatural elements?
He left blank spaces in the periodic table in the correct grouping and period that is where the newly discovered elements were placed.
What did Mendeleev predict about the periodic table?
The gaps in the first periodic elements described those elements which were not discovered at that time. Eg-silicon,germanium etc
Mendeleev's periodic table was accurate enough that he was able to use it to predict the existence and several properties of certain elements that had not yet been discovered true or false?
True.
How was mendeleyev able to predict the existence of elements that had not yet discovered?
Because there were gaps in the periodic table, which he invented. Unlike other scientist of the time who tried to make the elements fit theircategorising system, such as Newlands and his law of octaves, Mendeleev came to the conclusion that they had not discovered all the elements as he noticed patterns that allowed you to categorise elements if you left gaps that undiscovered elements could fill.
What is the important work of Dmitri Mendeleev?
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
How did many elements did Mendeleev predict would be discovered?
3
What led Mendeleev to predict some elements had not yet been discovered?
the large gaps
What led Mendeleev to predict that some elements had not yet been discovered?
the large gaps
Why couldn't Mendeleev predict the existence of the noble gases in the periodic table of elements?
He could predict other elements because there was an obvious gap, but he couldn't predict the noble gases because he didn't realize that there was going to be an 18th group since none of them were yet discovered. When he first started organizing the periodic table, the pattern still made sense even without the noble gases.
What enable Mendeleev to predict that certain elements would eventally be discovered?
U should know this.
How could Mendeleev predict the properties of elements that had yet not been discovered?
He used the difference method
