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
What element has more valence electrons that oxygen fewer valence electrons that neon more protons than sodium but fewer protons than argon?
there is no such element

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, although he did it differently we than it is right now. He pridected elements, and now, they've been discovered. Some people discovered elements Mendeleev didn't predict. Most of them were radioactive, like rutherfordium. (Of course, that element was synthetic. There are only 92 natural elements.) Mendeleev used different symbols than we do now, e.g. yttrium was Yt. The elements Mendeleev predicted were gallium, germanium, and scandium.
