Why did Dmitri make the periodic table?
Dmitri Mendeleev arranged the elements known at that time in the increasing order of atomic masses and repeating properties, so that it is easier to classify and study the properties of the elements.
Who was the first person to publish a periodic table?
Dmitri Mendeleev is credited with publishing the first widely recognized periodic table of elements in 1869. He organized the elements based on their atomic mass and predicted the properties of missing elements, allowing for future discoveries.
How many elements were on the first Periodic Table?
The initial development of the Periodic Table was attriibuted to Russian scientist, Dmitri Mendeleev.The first Periodic Table was published by Mendeleev in1869 and comprised 63 elements, arranged by their atomic masses and according to the increasing number of protons in their nucleus.
Who created the periodic table?
The first periodic table was developed by Dmitri Mendeleev in the mid-19th century.He wasn't the only person thinking along those lines ... both John Newlands and Lothar Meyer had proposed similar ideas However, Newlands was largely criticized and ignored at the time, and Meyer didn't make any predictions, so Mendeleev's table (which did make predictions about the properties of several as-yet-undiscovered elements) is generally regarded as the first.
What inspired Mendeleev to create his organization for the elements?
Mendeleev, a Russian chemist, organized the periodic table in order of relative atomic mass. He realized that the physical and chemical properties of chemicals were related to their atomic mass, and arranged them in a way so that groups of elements with similar properties fell into vertical columns (groups) with each period's elements having incrementally greater mass than the masses of the elements in the periods above it.According to Mendeleev, he had a dream about the elements falling into place on a table. His work was partly based on the work of Anton Lavoisier, who discovered the role of oxygenin combustion, and gave the element its modern name.

What year did Dmitri Mendeleev create the periodic table?
Dmitri Mendeleev created the periodic table in 1869, which organized the known elements based on their atomic properties and characteristics. Mendeleev's periodic table played a significant role in predicting the properties of undiscovered elements and has been the foundation of the modern periodic table.

Did Dmitri mendeleev find mendelevium?
Mendeleev came in a much earlier historical period than the discovery of mendelevium, which is named in his honor, because of his enormously important contribution to the science of chemistry.
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 invented piriodic table?
Dmitri Mendeleev created the first periodic table according to atomic mass in 1869. Others before Mendeleev had organized the elements according to their properties and were able to discern periodicity, although Mendeleev is generally accepted as the creator of the table.With the information he gathered about the elements, he was able to see that there were missing elements that hadn't been discovered. He could figure out the atomic masses of the missing elements by averaging the atomic masses of the elements above and below the missing one. One such element, which he called "eka-silicon" (eventually Ge) was missing, but with understanding of the patterns the periodic table made, he predicted the elements appearance, melting point, atomic mass, density, formula of oxide, and formula of chloride.Throughout the years, other scientists were able to find or create these missing elements to form the table we know today. Today's periodic table is ordered by atomic number instead of atomic mass (as Mendeleev had started). Henry Moseley was the first to order the elements by atomic number so elements would fit together in groups/families and periods better in 1913.
What did dimetri mendeleev find out about the periodic table?
Mendeleev arranged the elements in a table ordered by atomic mass, corresponding to relative molar mass as defined today.
