What did Dmitri create?
If you are talking about Dmitri Mendeleev, he was the first to come up with the first periodic table and the periodic law.
Where does technetium come in the periodic table?
Technetium is placed in the group 7 (manganese group) and period 5 of the periodic table of Mendeleev. The atomic number is 43.
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.
What two families does the element of calcium come from?
Two families ?? Calcium is an alkaline earth metal; located in group 2 and period 4 in the periodic table of Mendeleev.
What was the most important step in the development of the periodic table?
The most important step taken by Mendeleev in developing the periodic table of elements was the realization that chemical properties come in a repeating pattern, as elements get heavier. They go from metals to nonmetals to noble gases, and then back to metals.
Why is the periodic table come to be made?
Dmitri Mendeleev found 63 substances and organized them through atomic weight and grouping them by similarity of properties. Just organizes it, ya know :)
How is the modern periodic table different from Dmitri mendeleev's table?
The only important difference is that the modern periodic law must be framed in terms of atomic numbers, where Mendeleev framed the original periodic law in terms of atomic weights. There are only three places where this makes a difference. For cobalt and nickel Mendeleev assigned both exactly the same atomic weight -- well within the error margins at the time. For tellurium and iodine, Mendeleev insisted, wrongly, that the recognised atomic weight of tellurium was wrong, and that it had to be less than that of iodine. And the third case did not come up until later, because argon was not discovered until 1894 (element number 18, argon, has an atomic weight greater than that of element 19, potassium).
What family does zirconium come from?
In the periodic table, group IV: titanium, zirconium, hafnium. All are metals.
The first periodic table was arranged by?
Demitri Mendeleev. He arranged it by atomic mass
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.
Where does francium come in the periodic table?
Francium is in the period 7 and group 1 of the periodic table (alkali metals).
Did the periodic table come before the atomic model?
yes
