Independently by Dmitri Mendeleev and Lothar Meyer in 1869
The arrangement of the periodic table helped scientists predict the properties of missing elements based on their location in the table. For example, when Dmitri Mendeleev noticed gaps in the periodic table, he was able to predict the properties of the missing elements based on the neighboring elements, which ultimately led to the discovery of new elements like gallium and germanium.
Mendeleev attempted to organize the chemical elements based on their atomic mass and properties, creating the periodic table. He arranged the elements in rows and columns with similar properties to create patterns and predict the properties of unknown elements.
Mendeleev primarily used the element's atomic mass to classify them. He organized the elements into a periodic table based on their increasing atomic mass, allowing him to predict the properties of missing elements and arrange them in a logical order.
yes, properties of an element depends on its atomic number and atomic mass unless it is an exception and the atomic number and atomic mass of unknown elements are known by placing it in periodic table
Mendeleev developed the periodic table of elements by arranging the elements in order of increasing atomic mass in 1869. He discovered that elements with similar properties occurred in a periodic pattern. He was able to predict the properties of elements that were missing at the time because of this pattern. In 1914, Moseley contributed to the periodic table by reorganizing the elements according to atomic number.
Mendeleev believed that the properties of elements were based on their atomic weight. He arranged the elements in his periodic table according to their atomic weights, which allowed him to predict the properties of missing elements. This led to the discovery of new elements and the development of the modern periodic table.
Dmitri Mendeleev
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.
This is a very wordy response, but by setting up the Periodic Table according to elements' properties and characteristics, he was able to predict any given elements' properties because, with the way the Periodic Table is arranged, all of the elements surrounding any specific element would have similar properties to the element that they surrounded. For example, at the time there was no element known as Aluminum, but given the properties of the elements around that area (Group 13), he was able to correctly predict Aluminum's properties. When aluminum was discovered, Mendeleev's predictions were extremely close to the actual element's properties.

The reason the periodic table was created in the first place was to illustrate the "periodic" physical properties of the known elements of the time. Because of this, the properties of elements that were "missing" from the table could be extrapolated from the periodic trends seen in the known elements.
Mendeleev attempted to organize the chemical elements based on their atomic mass and properties, creating the periodic table. He arranged the elements in rows and columns with similar properties to create patterns and predict the properties of unknown elements.
Mendeleev's periodic table allowed for the prediction of the properties of unknown elements by identifying gaps in the table where elements had not yet been discovered. By examining the properties of neighboring elements, Mendeleev was able to predict the properties of the missing elements and suggest their existence. His periodic table provided a framework for organizing elements based on their atomic mass and chemical properties, which allowed for the accurate prediction of the properties of undiscovered elements.

Dmitri Mendeleev arranged the elements into rows and columns based on their atomic mass to show a recurring pattern of properties. This layout, known as the periodic table, allowed him to predict the properties of missing elements and demonstrate the periodicity of elemental properties.

Mendeleev arranged the known elements by increasing atomic mass and grouped elements with similar properties together. Gaps in the table indicated elements that were yet to be discovered. By observing the patterns in the properties of known elements within each group, Mendeleev was able to predict the properties of the undiscovered elements that would fill these gaps.
