Can you use the periodic table to predict the properties of undiscovered elements?

It is quite true that you can use the Periodic Table to predict the chemical properties of undiscovered elements, but this is not of any great practical importance because any remaining undiscovered elements are going to be so heavy that they will be very unstable, and will rapidly decay into other, lighter elements. All elements having a stable nucleus have already been discovered. Once you get to elements heavier than uranium, they just get more and more unstable, the heavier they get.

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.
Why did Dimitri Mendeleev predict that more elements with specific properties would be discovered?
because,he predicted some possible chemical formulas of the then undiscovered elements between the elements in his periodic table. so he concluded that more elements with specific properties would be discovered.
Was Mendeleev's periodic table accurate enough that he was able to use it to predict the existence and several properties of certain elements that had not yet been discovered?
Mendeleev was able to predict the properties of the elements that were not discovered at that time. He left gaps for these elements in his Periodic Table.
What can you use the Periodic Table of Elements for to predict about the elements?
An element's physical and chemical properties. You can also predict what elements will bond with each other.
What did Mendeleev predict about the periodic table?
The gaps in the first periodic elements described those elements which were not discovered at that time. Eg-silicon,germanium etc
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. ----

Who created the first version of the modern periodic table of elements and used it to predict undiscovered elements?
Dmitri Mendeleev
Why did Mendeleev called his arrangement of elements the periodic table?
If the elements (which were discovered by his time) were organized in the increasing order of their atomic weight, they will exhibit an apparent periodicity of properties. It also had the ability to predict physical and chemical properties of some undiscovered elements.

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 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.
Dmitri Mendeleev was particularly important why?
He is important because he was the person who invented the Periodic Table and made it how it is today
Was Dmitri Mendeleev able to predict undiscovered elements?
Dmitri Menedeleev was able to predict the properties of undiscovered elements because the periodic table organizes elements based on repeating properties. For example, all of the Noble Gases (the far-right column) have filled their valence electron shells and are inert gases. One could reasonably assume that if a new element was discovered that went in the noble gas column that it would be inert as well. Mendeleev used this concept to accurately predict the properties of a handful of undiscovered elements, such as Gallium and Germanium.
