Every element has a different atomic number. With the periodic table, they could organize accordingly to the subatomic particles.

How did the gaps on the periodic table help scientists look for undiscovered elements?
The gaps estimated their chemical properties.The elements when discovered were found to have those properties.They were then placed in these gaps.
What are the empty spaces in the periodic table meant for?
It was recognized by the inventor of the Periodic table that these empty spaces are for elements/isotopes that would be discovered someday. Dmitri Mendeleev is generally credited with the publication, in 1869, of the first widely recognized periodic table. He developed his table to illustrate periodic trends in the properties of the then-known elements. Mendeleev also predicted some properties of then-unknown elements that would be expected to fill gaps in this table.
Who was the father of the periodic table?
Father as in who created it? That would be Mendeleev, he even named the 101st element after himself. Improving: Mendeleev, was the father of the periodic table of elements, he discovered this method of organizinging the elements by playing a game of solitare with the chemical symbols.
How many elements are on the periodic table?
The first 92 (through uranium) occur naturally. The others are "transuranics." As of 2009, there are 118 ending with ununoctium. All together there are 117 elements on the periodic table, 94 of which occur naturally on earth. According to Wikipedia, there are 117 elements that have been isolated or synthesized, with a gap between element 116 and element 118. They do also show a wide (extended) format of periodic table with additional elements that have not been discovered, isolated, or synthesized on earth. See the related links below to see the standard and extended periodic tables.
How do you get the symbol of elements?
The symbol of elements can be found on a periodic table.
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.
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
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 is the greatest triumph about mendeleev's periodic table?
The greatest triumph of Mendeleev's periodic table was his predictions of the existence of the undiscovered elements.
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.
What element is no on the periodic table?
any of the elements who's existence we have proven is on the periodic table, if something isnt on the table it either hasn't been discovered, it isn't a pure element, or it doesn't exist
Are the element sin the periodic table the only elements discovered?
Yes. The elements in the Periodic Table are the only elements that have been discovered. However, we are still discovering and synthesising more elements.
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 was Mendeleev's contribution to the knowledge of elements?
When making his periodic table Mendeleev noticed some spaces where elements should be couldn't be filled. He didn't want to force elements that didn't belong there to go there, so he believed the spaces were undiscovered elements. He left the names blank but predicted their properties. Later the elements Mendeleev predicted existed were discovered.
Who discovered a pattern to the elements of the periodic table in 1869?
Demitri Mendeleev discovered a pattern to the periodic table in 1869.
What are the elements of a cola that can be found in your periodic table?
All of them, the periodic table has all of the elements the human discovered or made..
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.
