yes it is true. that is how the periodic table was established. ----
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.
Other scientists were skeptical about Mendeleev's periodic table because it contained gaps for elements that had not yet been discovered and because it did not follow strict atomic weights as a basis for organization. Additionally, there was skepticism about his prediction of the properties of undiscovered elements.
The gaps in Mendeleev's periodic table suggested the existence of undiscovered elements that would fit into the missing slots. This helped scientists predict the properties of these elements, aiding in their discovery. The periodic table's layout allowed for the systematic arrangement of elements based on their properties, making it easier for scientists to identify patterns and make predictions about unknown elements.
Mendeleev created the periodic table of elements. At his time, there was no grouping for the elements. He figured out that they can be grouped by mass and physical properties His result was so good that it correctly predicted elements that were not discovered yet.
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.

You think probable to Dimitri Mendeleev.
Scientists suggest Mendeleev left gaps in the periodic table because Mendeleev knew the elements existed; however, was unable to prove it.
The most important principle was the listing in groups, after similar chemical or physical properties.
Mendeleev's periodic table was considered a good model because it organized elements based on their atomic mass and properties, allowing for predictions of undiscovered elements and their properties.

Mendeleev developed the first periodic table and Mosely later modernized it.
Dmitri Mendeleev arranged elements on his first periodic table by increasing atomic mass and grouping elements with similar properties together. He left gaps for missing elements and predicted the properties of these undiscovered elements based on their position in the table.
The discovery of undiscovered elements with properties predicted by Mendeleev's periodic table (like gallium, germanium, and scandium) confirmed the accuracy of his organization. These elements filled gaps in the periodic table and established a pattern of periodicity that supported Mendeleev's initial insights.
