He made flashcards of elements and organized them in order of increasing atomic mass.
Dmitri Mendeleev created the periodic table to organize and classify the known elements based on their properties and atomic weights. He left gaps for undiscovered elements and successfully predicted the properties of some of these missing elements.
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.
No, Jakob Berzelius did not create the Periodic Table of Elements. The Periodic Table was developed by Dmitri Mendeleev in 1869. Berzelius did make significant contributions to the field of chemistry, such as introducing modern chemical symbols and determining the atomic weights of elements.
Dmitri Mendeleev was able to use his periodic table to make predictions because he organized elements based on their atomic mass and properties, revealing periodic trends. By identifying gaps in his table, he could anticipate the existence and characteristics of undiscovered elements. This predictive power was validated when elements like gallium and germanium were later found, aligning with Mendeleev's predictions. His systematic approach highlighted the underlying patterns in elemental properties, solidifying the periodic law.
Because the table is designed so that elements in the same column tend to have similar properties. The gaps at the top of the table are there to make the elements in vertical columns all have the same amount of outer-shell electrons.
No, Dmitri Mendeleev in Russia developed the first periodic table.
1869
He is the founder of the periodic table. He arranged the elements according to the atomic masses. Few changes are made in his periodic table to make the modern periodic table.
Mendeleev was working on a text book to use with his students.

Dmitri Mendeleev is credited with developing the periodic table of elements in 1869. He arranged the elements by increasing atomic mass, grouping together elements with similar properties. Mendeleev's table formed the basis for the modern periodic table.
Mendeleev's prediction that there were elements missing from the periodic table was confirmed when gallium was discovered in 1875 and germanium in 1886, fulfilling the gaps Mendeleev had left in his periodic table.
Dmitri Mendeleev created the periodic table to organize and classify the known elements based on their properties and atomic weights. He left gaps for undiscovered elements and successfully predicted the properties of some of these missing elements.
Dmitri Mendeleev is credited with putting together the first periodic table in 1869. Mendeleev arranged the elements based on their atomic mass, and left gaps for undiscovered elements which he predicted would fill those spaces.
He invented the periodic table. You must know what that means; he was the father of basic chemistry. Actually, he didn't discover the periodic table. He just arranged the only elements he had available in his day (not a lot) and arranged them based on patterns of # of protons, electrons, reactivity, etc. He didn't have an in-depth knowledge yet of electron configuration ;however, his "guess" turned out to have so many great implications that we now use his invention everyday everywhere.
There have been two make ups of the periodic table so far Mosley made the first one but was overtaken by Dimitri Mendeleev's form, which we use today.
Dmitri Mendeleev was the first scientist to create the periodic table
