Mendeleev arranged the elements in order of increasing related Atomic Mass
What else can I help you with?
What did Dimtri Mendeleev did not know about the periodic table?
Only some elements were discovered during the life of Mendeleev.
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.
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).
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.
What did Dmitri Mendeleev do during the Industrial Revolution?
Mendeleev laid the foundation for theperiodictable that we know today
History of periodic table?
The history is that Dymitry Mendeleev is the inventer of long time periodic table that's all i know
What is M periodic table?
The M periodic table, or Mendeleev's periodic table, is a historical version of the periodic table created by Dmitri Mendeleev in 1869. It organized elements based on their atomic mass and properties, leading to the prediction of undiscovered elements. Mendeleev's table highlighted periodic trends and allowed for the arrangement of elements into groups with similar characteristics. While modern periodic tables are organized by atomic number, Mendeleev's work laid the foundation for the development of the periodic table as we know it today.
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.
Who made the first periodic table?
Dimtrii Mendeleev made the first Periodic Table. dmitry mendeleev
Is Dmitri Mendeleev really Hagrid?
Dmitri Mendeleev is the inventor of the periodic table. As far as I know, he is completely unrelated to Rubeus Hagrid from the Harry Potter stories, or to any other Hagrid.
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
Why would Mendeleev's periodic table be smaller than the one we know today?
Because back in 1869 they didn't know all of the periods that we know today.
