The five properties Mendeleev used in his table were Atomic Mass, chemical properties, valency (oxidation state), color, and density.

The Periodic table
True. Mendeleev used his periodic table to predict the properties of undiscovered elements by leaving gaps for them based on the patterns he observed in the properties of known elements. His predictions were later confirmed with the discovery of elements like gallium and germanium, which closely matched his forecasts. This ability to predict properties based on periodic trends is a key aspect of the periodic table's significance in chemistry.
This scientist is the Russian chemist Dimitri Mendeleev.
The five properties used to explain the behavior of sound waves are frequency (pitch), amplitude (loudness), wavelength, speed, and direction. These properties help describe how sound waves travel and interact with different mediums.
It's probably Mendeleev you're after. He came up with the first version of a Periodic Table of the elements, and used this to predict the properties of elements that hadn't been discovered at that time.
Mendeleev used the properties of gallium, scandium, and germanium to predict their existence before they were discovered. Their discovery and properties helped confirm the accuracy of Mendeleev's periodic table and his periodic law. This further solidified Mendeleev's contributions to the development of the modern periodic table.

Mendeleev arranged elements based on their atomic weights and chemical properties. He noticed that when he arranged elements in order of increasing atomic weight, certain properties repeated at regular intervals, leading to the development of the periodic table.
The Periodic table
One scientific method that could be used to predict the properties of an element is the periodic table. By examining an element's position on the periodic table, one can make predictions about its atomic structure, reactivity, and physical properties based on trends and patterns observed among elements in the same group or period.
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.

So you can classify the elements into groups.
