properties. Mendeleev's periodic table had gaps for elements that had not been discovered yet, but he was able to predict their properties based on the patterns of the elements surrounding the gaps. This led to the discovery of new elements like gallium, germanium, and scandium.
The periodic table was first developed by Russian chemist Dmitri Mendeleev in 1869. He arranged the elements based on their atomic mass and properties and predicted the properties of missing elements. Over time, the periodic table has been modified and expanded based on the discovery of new elements and advancements in atomic theory.
Dmitri Mendeleev published the first periodic table in 1869. He built on the work of several other scientists, including Antoine Lavoisier, Johann Dobereiner, Alexandre-Emile Beguyer de Chancourtois, and John Newlands, who had previously studied the best way to classify the elements.
Yes, there have been several versions of the periodic table developed over time. The current version is based on Dmitri Mendeleev's layout, which arranges elements by their atomic number and chemical properties. Different scientists have made adjustments and improvements to the periodic table as new elements have been discovered.
The number of non metals (excepting metalloids) in the periodic table of Mendeleev is 17; several other elements are sometimes consideredas non metals.
Dmitri Mendeleev predicted the existence and properties of several elements that were later discovered and filled gaps in the periodic table. He also predicted the properties of these elements based on their position in the periodic table.
When making his periodic table Mendeleev noticed some spaces where elements should be couldn't be filled. He didn't want to force elements that didn't belong there to go there, so he believed the spaces were undiscovered elements. He left the names blank but predicted their properties. Later the elements Mendeleev predicted existed were discovered.
You think probable to Dimitri Mendeleev.
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 was widely accepted by the scientific community, particularly after he accurately predicted the properties of several missing elements. Among those who agreed with his theories were chemists Julius Lothar Meyer and William Ramsay. Mendeleev's periodic table provided a comprehensive framework for understanding the relationships between elements based on their properties.

Dimitri Mendeleev developed the law of periods and the periodic table, and described the properties of several elements before they were isolated by scientists.

True.
