What elements has a ground-state electron configuration different from the predicted one?
There are many elements among the transitional elements which has the electron configuration differed than predicted. Such element with the lowest atomic number is chromium.
From gaps in his table mendeleev predicted the existence of several elements and their?
Atomic numbers.
How many elemnts are there?
112 elements have been named and six more predicted.
Who listed the elements in a table accourding to their atomic masses?
Mandeleev who predicted periodic table.
Mendeleev left spaces in his periodic table and predicted several elements and they're?
atomic numbers
Why were some of the elements not predicted?
After Mendeleev all natural elements were predicted.
What are some of the uses of the periodic table of elements?
- allowed rational ordering of chemical elements- predicted the properties of unknown elements- the chemical behavior of chemical elements can be predicted- the atomic radius can be predicted- the melting point can be predictedand more
What kinds of predictions did Mendeleev make using his table?
By placing the elements in order of their Atomic Mass then grouping them based on similar chemical properties, Mendeleev recognized that there were gaps in the pattern he made where elements should be. He predicted there were some elements yet to be discovered and predicted their chemical properties. The elements he predicted were later discovered and named germanium, gallium, and scandium.
What did the gaps on Mendeleev's tabel represent?
He predicted that elements with the predicted properties would be discovered to fill in these gaps.
What elements properties can be predicted from?
An elements property can be best predicted from the group it is in the Periodic Table. Groups (the columns of the tables) of elements have similar properties due to their similar electron configuration of the valence shell.
What elements has a ground-state electron configuration different from the predicted one?
There are many elements among the transitional elements which has the electron configuration differed than predicted. Such element with the lowest atomic number is chromium.
The usefulness of Mendeleev's periodic table was comfirmed by?
The usefulness of Mendeleev's periodic table was confirmed by the discovery of elements with predicted properties.
What properties can be predicted by the elements place on the periodic table?
Monkey123 will fly p456urple
From gaps in his table mendeleev predicted the existence of several elements and their?
Atomic numbers.
How many elemnts are there?
112 elements have been named and six more predicted.
Who predicted that the existence of several missing elements?
You think probable to Dimitri Mendeleev.
When can light elements be predicted to have stable nuclei?
When the neutron:proton ratio is 1:1
