Why did mendeleev leave gaps in the table?
Scientists suggest Mendeleev left gaps in the periodic table because Mendeleev knew the elements existed; however, was unable to prove it.
What did Dimtri Mendeleev did not know about the periodic table?
Only some elements were discovered during the life of Mendeleev.
Why was mendeleev's periodic table valid at all?
His table was sorted by atomic mass, not atomic number. (the way today's periodic table is sorted) Mendeleev was almost right, but they did not know about protons at the time. (atomic number is the number of protons in an element) There would have been absolutely no way of him figuring out they were related to atomic number if he didn't even know about atomic number
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).
Did mendeleev know about protrons?
No, Dmitri Mendeleev did not know about protons. The concept of protons was not discovered until later in the 20th century, after Mendeleev's time. Mendeleev is most famous for creating the periodic table of elements.
Who organized the very first periodic table?
The first periodic table was organized by Dmitri Mendeleev in 1869. Mendeleev arranged elements according to their atomic weight and properties, leaving gaps for unknown elements that were later discovered.

Scientists suggest Mendeleev left gaps in the periodic table because Mendeleev knew the elements existed; however, was unable to prove it.

History of periodic table?
The history is that Dymitry Mendeleev is the inventer of long time periodic table that's all i know

What did Dmitri Mendeleev arrange into a systematic chart?
Dmitri Mendeleev arranged the known chemical elements into a systematic chart known as the periodic table. His arrangement was based on the elements' atomic mass and chemical properties, leading to the organization of elements in periods and groups. Mendeleev's periodic table laid the foundation for the modern understanding of the relationship between elements.
What did Dmitri Mendeleev do during the Industrial Revolution?
Mendeleev laid the foundation for theperiodictable that we know today
Who is Dmitri Mendalev?
I do not know but Dmitri Mendeleev was born at Tobolsk, Siberia in 1834 and died in 1907. Mendeleev studied science at St. Petersburg and graduated in 1856. In 1863 Mendeleev was appointed to a professorship and in 1866 he succeeded to the Chair in the University. Mendeleev is best known for his work on the periodic table; arranging the 63 known elements into a Periodic Table based on atomic mass, which he published in Principles of Chemistry in 1869.
Who was the scientist that organized the elements into a table that you use today and what was the table called?
i don't know the scientist but it is the periodic table of the elements
Mendeleev's periodic table did not include the group we now know as noble gases What might be the reason?
During Mendeleev's time, noble gases were not discovered yet. They were later discovered in the late 19th and early 20th century, after Mendeleev had created his periodic table.
