Mendeleev was a Russian chemist who organized the periodic table.
Mendeleev did not predict the properties of silicon.
Dimitri Mendeleev was born on February 8th, 1834.
No, Dmitri Mendeleev did not know about protons. The concept of protons was not discovered until later in the 20th century, after Mendeleev's time. Mendeleev is most famous for creating the periodic table of elements.
Scientists in 1750 did not have access to the vast amount of experimental data on elements that Mendeleev had. The understanding of atomic theory, periodic trends, and chemical behavior was not advanced enough at that time to support the development of a table like Mendeleev's. Additionally, the technology and resources needed to collaborate and disseminate scientific information were also lacking in 1750.
Mendeleev realized that some elements had not been discovered.

Mendeleev arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
Dmitri Mendeleev
He was Russian
Dmitri Mendeleev was the first to develop the modern periodic table in 1869. Later, Henry Moseley rearranged the elements by atomic number, which is the modern arrangement. So, Mendeleev comes before Moseley in terms of their contributions to the modern periodic table.
Dmitri Mendeleev is credited with developing the periodic table in a form close to its modern version. He arranged the elements based on their properties and left gaps for undiscovered elements, predicting their properties accurately. This work was inspired by his experience organizing playing cards into sets.
Well, first of all, all the elements that were on the table that Mendeleev made weren't discovered yet (i.e. Gallium) and the game of Solitaire, which helped to inspire Mendeleev to put them into rows and columns, hadn't been invented yet either. (hope this helps to anyone who is looking at this for their science class) :)
The two earlier scientists whose ideas Dmitri Mendeleev combined were Antoine Lavoisier and John Dalton. Lavoisier established the law of conservation of mass, while Dalton introduced the atomic theory by proposing that all matter is composed of atoms. Mendeleev built upon these concepts to develop the periodic table of elements.
Mendeleev chose to order the known elements by mass because he observed that there was a pattern in the physical and chemical properties of elements when they were arranged by increasing atomic mass. This led him to develop the periodic table, where elements with similar properties were grouped together.
Mendeleev did not predict the properties of silicon.
