What characteristics of solitaire did Mendeleev use as a model for his periodic table?
He wrote a card for each element, with their name,atomic mass & chemical properties on,then laid them out like a game of solitaire
Who redesigned the periodic table to put elements in order by atomic number?
No,its not Dmitri Mendeleev.Dmitri Mendeleev create the first periodic table but mostly it was wrong....he arranged them by the atomic number when it should have been by increasing the atomic number(and ya there's a difference)..the one that rearranged it was Henry Moseley.
How Mendeleev used the data available to him to create his periodic table?
Mendeleev placed his elements in order of increasing atomic mass. He placed elements with similar chemical properties in the same groups or families. He realized that there were some gaps in the table where an undiscovered element should go and made predictions about those elements before they were found.
Did Mendeleev noticed a definite pattern in the valence of the elements?
the samepattern for how many protons all elements have to they are all factors of each other. That is why the periodic table is set up the way it is in that awkward shape
WERE DID the periodic table come from?
The periodic table of elements was first created by Dmitri Mendeleev in 1869. He was a Russian chemist who arranged all the elements (known to man at that time period) in order of increasing atomic number. He found that each one resembled the 8th element following it in appearance, properties, and activity.
What trends were seen in Mendeleev's periodic table?
he arranged his Periodic Table by each elements Atomic Mass
How many regions are there in the periodic table with in each element?
The periodic table of Mendeleev has 18 groups and 7 periods.
What family does nitrogen belongs to?
On the periodic table, the family nitrogen belongs to is Group Vb. In their outer electronic shell, each of the elements within this group have five electrons.
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
How do the atomic numbers of the elements with in each of group 1 2 and 13-18 of the periodic table vary?
Mendeleev's Periodic Table -- the reason for periodicity -- is explained by the arrangement of the electrons around the nucleus. *Read your chemistry book* :D
What does period mean in the periodic table?
Periodic means repeating. When Mendeleev was rearranging the elements, he noticed that some of their properties matched with one another about every eight elements. Thus, when the elements are arranged in the rows of the Periodic Table, they also have matching properties in each column.
What is the science of Mendeleev's research?
Well Mendeleev constructed the first well detailed periodic table based on the atomic masses of each element. The elements were arranged in an increasing order of their atomic masses. His principle was that the increasing atomic mass determines the periodic properties of each element. This eventually led him to predict new elements. But his table had some flaws one of them being that hydrogen had same characteristics as that of alkali metals and halogens. Another being that the isotopes had no place in the periodic table.
How will the identity and properties of the chlorine change in each case when a proton is added to each case?
Chlorine has 17 protons; the next chemical element in the periodic table of Mendeleev is argon with 18 protons.
What element is unreactant?
All the elements in the Inert Gases family (exc. Radon) are highly unreactive. The Inert Gases family occupies Group 18(0) of the Periodic Table. They each have 8 electrons in the outer shell. The Inert Gases Group contains;HeliumNeonArgonKryptonXenonRADON

Why did Dmitri mendeleev reverse the order of some elements in the periodic table?
He was bold enough to reverse the order of some pairs of elements and to predict that their atomic masses were incorrect. Some of these predictions were correct, but others were not, because we now know that the fundamental basis of the periodic table is atomic number rather than atomic mass.
