Dmitri Mendeleev is credited with the creation of the modern periodic table in 1869. He arranged the elements based on their atomic mass and properties, predicting the existence of yet-to-be-discovered elements and leaving gaps for them in the table.
Dmitri Mendeleev is credited with creating the periodic table of elements. He organized elements by their atomic mass and properties, which led to the development of the modern periodic table.
Dmitri Mendeleev is credited with developing the modern periodic table in 1869. He arranged the elements based on their atomic mass and chemical properties, predicting the properties of undiscovered elements. Mendeleev's table laid the foundation for the periodic table we use today.
Dmitri Mendeleev is credited with the creation of the periodic table. He arranged the elements based on their atomic mass and chemical properties, and left gaps for undiscovered elements. His work laid the foundation for our modern understanding of the periodic table.
Dmitri Mendeleev is credited with creating the Periodic Table of Elements in 1869. He arranged elements by increasing atomic weight and noticed periodic trends in their properties which led to the development of the modern periodic table.
Periodic table of elements, which he arranged by atomic weight and properties to predict the existence of undiscovered elements. His table laid the foundation for the modern periodic table used today in chemistry.
Dmitri Mendeleev is credited with developing the modern periodic table in 1869. He arranged the elements based on their properties and atomic weights, predicting the properties of undiscovered elements.
Dimitri Mendeleev is credited with the the creation of the first modern and rational periodic table of chemical elements; but other chemists also had contributions.
Dimetri Mendeleev was a Russian chemist. He is credited for his version of periodic table which was better than anyone else's during that time. He organized elements almost accurately and formed the basis for the Modern Periodic Table.
There are 7 periods in the modern periodic table.
The modern periodic table has seven periods.
