What contribution did Dmitri Mendeleev make in chemistry what was he able to do to show the valeu of his contribution?
Dmitri Mendeleev created the periodic table of elements, arranging elements by atomic mass and properties. His contribution revolutionized the field of chemistry by predicting the existence and properties of undiscovered elements. Mendeleev's periodic table provided a framework for understanding the relationship between elements and laid the foundation for modern chemistry.
What was Dmitri Mendeleev's accomplishments?
In 1869, he published the greatest of his works, Principles of Chemistry, where he formulated his famous periodic table, translated into many languages ​​and that was a textbook for many years.
Why Mendeleev was able to observe periodicity?
mendeleev arranged elements according to atomic mass. He was able to observe periodicity when arranged in this pattern.
What was Mendeleev able to find out for each element?
He was able to work out the atomic mass of the missing elements, and so predict their properties. And when they were discovered, Mendeleev turned out to be right. For example, he predicted the properties of an undiscovered element that should fit below aluminium in his table. When this element, called gallium, was discovered in 1875, its properties were found to be close to Mendeleev's predictions. Two other predicted elements were later discovered, lending further credit to Mendeleev's table.
Who are the scientist and their contribution in development of periodic table?
.In 1869 the Russian chemistry professor Dmitri Ivanovich Mendeleev and four months later the German Julius Lothar Meyer independently developed the first periodic table, arranging the elements by mass. its invention though is generally credited to Russian chemist Dmitri Mendeleev . The layout of the table has been refined and extended over time, as new elements have been discovered. In the 1940s Glenn T. Seaborg identified the transuranic lanthanides and the actinides, which may be placed within the table, or below

Mendeleev's periodic table provided a framework for understanding the relationship between elements and laid the foundation for modern chemistry.
Who is the inventor of the periodic table?
Dmitri Mendeleev is generally credited, as he was able to predict the properties of elements which had not yet been discovered based on 'gaps' in his table. He ordered the known elements in terms of their atomic mass in 1869; elements are listed in order of increasing atomic number in the modern version.
What is the main contribution of Dmitri Mendeleev in modern chemistry?
He made the periodic table. When he found gaps he said there were unknown elements, he was right and those elements were found in his lifetime.Mendeleev was the first person to organize the elements into what we would recognize as a version of the modern periodic table.
How was Dmitri Mendeleev able to predict the properties of germanium?
Dmitri Mendeleev was able to predict the properties of germanium by leaving gaps in his periodic table for elements that were yet to be discovered. He noticed a pattern in the properties of known elements and used this pattern to predict the existence and properties of undiscovered elements, such as germanium.
Mendeleev made the first periodic table around?
Dmitri Mendeleev created the first periodic table of elements in 1869. He arranged elements by increasing atomic weight and grouped those with similar properties together. Mendeleev left gaps for undiscovered elements and was able to predict the properties of these missing elements.
Was mendeleev able to gather information from scientists internationally?
Yes, Dmitri Mendeleev was able to gather information from scientists internationally, as he corresponded with and utilized research from chemists around the world. His periodic table was influenced by the work of scientists like John Newlands, Lothar Meyer, and others, showcasing a collaborative scientific environment. Mendeleev's ability to synthesize this global knowledge was crucial in developing his periodic classification of elements.
What was Dmitri Mendeleev's accomplishments?
In 1869, he published the greatest of his works, Principles of Chemistry, where he formulated his famous periodic table, translated into many languages ​​and that was a textbook for many years.
What did Dmitri Mendeleev find when he organized the elements by mass?
I believe the correct answer is he was able to predict the existence of yet undiscovered elements, due to the gaps. For instance, I believe germanium was one of the elements undiscovered in the table, its placeholder was called ekasilicon.

Who arranged the periodic table according to increase in atomic weights?
Dmitri Mendeleev, a Russian scientist. He arranged cards in atomic weight order and noticed patterns (periods). This resulted in him being able to guess which elements were missing and complete the periodic table.
