Why did Mendeleev place more than one element in the same place?
Mendeleev placed more than one element in the same position on his periodic table because he prioritized the atomic mass of elements over their atomic number, leading to instances where similar properties grouped elements together. Additionally, he recognized that some elements had not yet been discovered, and leaving gaps allowed for the prediction of their properties. This arrangement helped to illustrate the periodicity in elemental properties, even if it meant placing multiple elements in the same position.
How mendeleev's table was able to cope with new discoveries more easily than newlands' or dobereiner's systems?
The Mendeleev table is more complex and rational.
What planets have more than one element?
Many of the planets have more than one element. Two of these planets that have more than one element are Earth and Jupiter.
What takes place within the atoms of a material when the material is positively charged?
there are more neutrons than a usual atom of a certain element
How is moseleys basis for arranging the elements different from mendelees?
Moseley's basis and Mendeleev's basis both involved experimental measurements. But Moseley's involved X-ray properties, and X-rays were not discovered when Mendeleev first stated the Periodic Law. Atomic weight and atomic number follow nearly the same sequence, but there are three cases of reversal of order: Argon element 18 atomic weight 40.0; potassium element 19 atomic weight 39.1. (Argon was not discovered until 1894; first periodic table 1869). Cobalt element 27 atomic weight 58.9; nickel element 28 atomic weight 58.7. (Very small difference; Mendeleev gave these two elements identical atomic weights) Tellurium element 52 atomic weight 127.6; iodine element 53 atomic weight 126.9 (Major problem for Mendeleev -- he insisted that the atomic weight of tellurium had to be 125, but careful re-measurements continued to show 127.5-128) Moseley's atomic number is definitely a better basis for the periodic law than Mendeleev's original suggestion of atomic weight.

What were the names of three elements Dmitri Mendeleev predicted from the blank spaces that Dmitri Mendeleev on the periodic table?
http://en.wikipedia.org/wiki/Mendeleev%27s_predicted_elements It says he predicted more than three.
What element contains more than one element and has metallic properties?
No element contains more than one element.
What planets have more than one element?
Many of the planets have more than one element. Two of these planets that have more than one element are Earth and Jupiter.
Is Dmitri Mendeleev a better scientist than Jacques Cousteau?
yes he made alot more thing
What element has more known compounds than any other element?
I would expect Carbon to be the element that forms more compounds than any other element.
Which element is usually found more often in speeches than in written essays?
A theme that takes the place of a detailed explanation
When did Dmitri mendeleev start his research of the periodic table?
DMITRY MENDELEEV WAS BORN ON FEBRUARY 8,1834.HE WAS KNOWN AS THE CHEMIST WHO CREATED THE PERIODIC TABLE. BY THE YEAR OF 1869 MENDELEEV PUBLISHED HIS PERODIC TABLE. IN THE YEARS BETWEEN 1859-1861 MENDELEEV STARED HIS RESEARCH. HE WAS A AVERAGE STUDENT AND A COLLEGE GRADUATE. MENDELEEV WOULD ALWAYS BE REMEMBERD FOR THE DEVELOPMENT OF THE NEW PEROIDC TABLE
Why did mendeleev place tellurium before iodine?
Iodine's atomic number is 53 whereas tellurium's is 52. Atomic number is basically the number of protons that an element has. Therefore, as iodine has more protons than tellurium, it appears later in the table.
What takes place within the atoms of a material when the material is positively charged?
there are more neutrons than a usual atom of a certain element
Who discovered the periodic table of element?
Dmitri Mendeleev first accomplished the putting together the periodic table and publishing in 1869. Dmitri was not the first to think of the periodic table, but in fact built upon the work of others before him, mainly Antoine-Laurent de Lavoisier and John Newlands.
