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.
How did Mendeleev place germanium on the periodic table?
Mendeleev was able to predict the properties of the yet unknown element (Germanium) by the properties of the surrounding known elements on his periodic table of the elements. Predicting properties such as reactivity, density, atomic mass, etc., he knew where the undiscovered element would be placed.
What came first the periodic law or the periodic table?
The periodic law came first. Mendeleev enunciated this law as "when the elements are arranged in order of increasing atomic weight, there is a periodic repetition of their chemical properties". He proceeded to construct a table based around this law. In constructing the periodic table Mendeleev used remarkable chemical insight, changing the atomic weights of several elements, atomic weight and valence of a few, and leaving a few spaces where there seemed to be room for an undiscovered element in the table -- he was able to predict the chemical properties of these then undiscovered elements with amazing accuracy.
Why did mendeleev leave gaps in the table?
Scientists suggest Mendeleev left gaps in the periodic table because Mendeleev knew the elements existed; however, was unable to prove it.
What properties did mendeleev use to arange the the periodic table?
He used mass,what they react to and there proertys

What is the greatest triumph about mendeleev's periodic table?
The greatest triumph of Mendeleev's periodic table was his predictions of the existence of the undiscovered elements.
What is the probable sequence in which the following clades of animals originated from earliest to most recent?

Is it true or false that Mendeleev and other scientists were able to use the periodic table to predict the properties of undiscovered elements?
yes it is true. that is how the periodic table was established. ----
What Is The Correct In Which Organisms Appear In The Fossil Record from earliest to most recent?
mendeleev creates a Periodic Table mendeleev predicts undiscovered elements moseley arranges the periodic table by atomic number a periodic table is created by mendeleev mendeleev predicts undiscovered elements the periodic table is arranged by atomic number by a man named moseley
What is Dmitri Mendeleev most known for?
Dmitri Mendeleev was a Russian inventor and chemist. He is perhaps best known for his version of the periodic table. This helped him predict properties of elements which had not yet been discovered at that time.
What are the two factors that led to widespread acceptance of Mendeleev's periodic table?
Mendeleev table allow predictions on the elements undiscovered at the time.

What method did Dmitri Mendeleev use to arrange his periodic table.?
He arranged elements in order of increasing atomic masses. He left gaps for undiscovered elements.The elements with same properties were grouped together.
What properties did mendeleev use to arange the the periodic table?
He used mass,what they react to and there proertys
