What was Mendeleev's contribution to the knowledge of elements?
When making his periodic table Mendeleev noticed some spaces where elements should be couldn't be filled. He didn't want to force elements that didn't belong there to go there, so he believed the spaces were undiscovered elements. He left the names blank but predicted their properties. Later the elements Mendeleev predicted existed were discovered.
Who devised the periodic table of elements?
Dmitri Ivanovich Mendeleyev. Another spelling of his name is Dmitri Ivanovich Mendeleev.
Mendeleev studied the properties of elements and looked for?
Patterns
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.
What chemicals did Dmitri Mendeleev omit from the periodic table?
The Mendeleev-style periodic table omits all of the elements from groups 3-12 (also known as the d-block elements) by including them in the main group.
What elements did mendeleev group with lithium?
hydrogen
True or false mendeleev also grouped elements that has similar properties?
Yes. Mendeleev did group elements in similar properties.
What do you meant by family of elements?
"Family of elements" is the synonym of group (column) in the periodic table of Mendeleev.
Did Mendeleev group elements that had similar properties true or false?
It is true.
What group is the element iodine in?
The Halogens. Other elements in this group are Fluorine, Chlorine, Bromine and Astatine.
Classifying to What group of elements does an atom elements x belong?
Search this element in the periodic table of Mendeleev.
Did mendeleev group the elements by density?
Chemistry books say that he grouped the elements by atomic weight. That is not the same as density.
Alkali metals are the elements in the what column?
Alkali metals are in the first column (group) of the Mendeleev periodic table of elements.
What is the group name of the element bohrium?
Group 7 of the periodic table of Mendeleev and period 7 (transfermium elements).
What elements did Mendeleev group with lithium in his periodic table?
alkaline metal group(or the group 1 elements, except for hydrogen(H), which is a group 1 element but not an alkali metal) - lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
What is O family name in the periodic table of elements?
Oxygen is in the group 16 of the periodic table of Mendeleev - chalcogenides group.
