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
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 is usually credited as the first person to do so. Subsequently, chemists learned to arrange the elements by atomic number rather than atomic mass.
Mendeleev discovered gaps in his periodic table where elements should logically fit based on their properties and atomic weights. He predicted that these missing elements would eventually be discovered because there were clear patterns in the properties of known elements that suggested the existence of undiscovered elements to complete the table.
Mendeleev was able to predict the properties of the elements that were not discovered at that time. He left gaps for these elements in his Periodic Table.

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 was able to predict the properties of germanium by leaving gaps in his periodic table for elements that were yet to be discovered. He noticed a pattern in the properties of known elements and used this pattern to predict the existence and properties of undiscovered elements, such as germanium.
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.
By looking at the properties of elements he knew about, finding repeating patterns and noticing that there seemed to be elements that were missing from his table. A simple example from maths: What's the missing number in this list? 1, 2, 3, 5, 6, 7... and the answer is: it is 4 and it has the property of being an even 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.
The Mendeleev table, also known as the periodic table, was organized by atomic number, atomic mass, and chemical properties of elements. Mendeleev was able to predict the properties of missing elements based on the gaps in his table.
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.
