An element's atomic number, or how many protons it has.
Atomic weight.
Dmitri Mendeleev is the chemist credited with developing the periodic table in 1869. His arrangement of elements by atomic mass and chemical properties formed the basis for the modern periodic table.
Dmitri Mendeleev is credited with creating the periodic table, a method for arranging elements based on their properties and atomic number. This arrangement allows for predicting the properties of elements that had not yet been discovered at the time.
According to Dmitri, properties of elements are periodic function of their atomic masses. He placed elements possessing same chemical properties together.
He mostly used this: -How much atomic mass (at first he used this method but he later corrected it to this:) -atomic number or the number of protons He used this to determined the order of the periodic table together:)
Dmitiri Mendeleev arranged the Periodic Table of elements in order of increasing atomic masses.
Dmitri Mendeleev organized the elements based on their atomic mass, grouping similar elements together and leaving gaps for undiscovered elements. This led to the creation of the periodic table, where elements with similar properties were placed in the same column.
Father as in who created it? That would be Mendeleev, he even named the 101st element after himself. Improving: Mendeleev, was the father of the periodic table of elements, he discovered this method of organizinging the elements by playing a game of solitare with the chemical symbols.

Dmitri Mendeleev is the chemist credited with developing the periodic table in 1869. His arrangement of elements by atomic mass and chemical properties formed the basis for the modern periodic table.
Dmitri Mendeleev is credited with creating the first version of the periodic table in 1869. Mendeleev arranged the elements by atomic mass and predicted the properties of undiscovered elements. Subsequent scientists, such as Henry Moseley, contributed to refining and organizing the periodic table based on atomic number.
Dmitri Mendeleev is credited with creating the periodic table, a method for arranging elements based on their properties and atomic number. This arrangement allows for predicting the properties of elements that had not yet been discovered at the time.
Dmitri Mendeleev was the Russian chemist who developed the periodic table of elements. He accomplished most of his work during the 1860s. In 1869, he invented a method of arranging the elements that were known at that time in order of their atomic weights.
According to Dmitri, properties of elements are periodic function of their atomic masses. He placed elements possessing same chemical properties together.
Dmitri Mendeleev arranged his periodic table by increasing atomic mass and grouping elements with similar properties in columns. He left gaps for undiscovered elements and predicted their properties based on the patterns he observed. This periodic table formed the basis for the modern periodic table we use today.
Dmitry Ivanovich Mendeleev published his work on the periodic table in 1869. His periodic table arranged elements by increasing atomic weight and was a significant contribution to the field of chemistry.
The periodic table is a tool used in science to organize and display all known elements based on their atomic structure and properties. It helps scientists in understanding patterns in element behavior, predicting the properties of unknown elements, and guiding research and experimentation. The periodic table plays a fundamental role in the scientific method by providing a clear framework for organizing and studying the elements.
