those were for the new elements which were yet to be discovered which may be inert in nature. e.g. argon neon krypton etc.

What are the elements whose discovery added an entirely new row to Mendeleev's periodic table?
The Noble Gases, It added a new "Group" to the periodic Table.
Development of periodic table?
The modern periodic table of the elements was published by Dimitri Mendeleev in 1869. Several new elements have been discovered and added to the table since then.
How many periodic tables have there been?
Mendeleev's created the periodic table in 1869 since then it has been as new discoveries have been made
How can you compare and contrast the periodic table that Mendeleev developed to the periodic table that Mosley organized?
Mendeleev used atomic masses to classify the element, where as Moseley classified the element in terms of atomic number, he suggested that chemical and physical properties are the functions of the atomic number Elements in the periodic table is classified as Metals, Nonmetal and Metalloids. Normally Group 1 to 12 are metals... Sayed Abdul Aziem Sayed_abd2007@hotmail.com
What year was Dimitry Ivanovich Mendeleev's work on the periodic table published?
The periodic table of the chemical elements is a tabular method of displaying the chemical elements. Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869. Mendeleev intended the table to illustrate recurring ("periodic") trends in the properties of the elements. The layout of the table has been refined and extended over time, as new elements have been discovered, and new theoretical models have been developed to explain chemical behavior. "Periodic Table."

When did mendeleev create a new row on the periodic table?
Mendeleev created a new row on the periodic table every time chemical properties were repeated.
When did mendeleev create a new row in his periodic table?
Mendeleev supposed that a new row is necessary in the periodic table after the discovery of lanthanoides.
One of the important ideas about Mendeleev's periodic table was that he predicted new?
Gaps
How did Dmitri Mendeleev discover the periodic table with noble gases?
When Mendeleev proposed his periodic table, the noble gases had not been discovered, so they did not play a part in his development of the periodic table.
How was Mendeleev's periodic table validated?
The confirmation is that new elements discovered have been correctly inserted in table.
Who recognized a pattern in the properties of the elements and made the first periodic table?
In 1869, a Russian scientist named Dmitri Mendeleev arranged the elements in a table according to their atomic mass, this was the first periodic table. However, a few elements didn't fit the pattern in Mendeleev's table, so a new table had to be made, and that table is today's periodic table which is arranged by atomic number, and not atomic mass.
What changes were to the periodic table after Dmitri Mendeleev discovery?
they changed the 3 new Elements.
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 are the elements whose discovery added an entirely new row to Mendeleev's periodic table?
The Noble Gases, It added a new "Group" to the periodic Table.
Development of periodic table?
The modern periodic table of the elements was published by Dimitri Mendeleev in 1869. Several new elements have been discovered and added to the table since then.
Who wrote or found the periodic table of elements?
The periodic table of elements was created by Dmitri Mendeleev, a Russian chemist, in 1869. He arranged the elements based on their atomic mass and properties, and left gaps for elements that were yet to be discovered. Over time, new elements were discovered and added to the periodic table by various scientists.
How many periodic tables have there been?
Mendeleev's created the periodic table in 1869 since then it has been as new discoveries have been made
