How did the Russian scientist Dmitry Mendeleev discover the Periodic Table of the Elements?

Dmitri Ivanovich Mendeleev was born on February 8, 1834 in the Russian city of Tobolsk as the seventeenth and youngest child in the family. His father, Ivan Pavlovich Mendeleev, was the director of the gymnasium. The self-willed and talented son Dmitri gave his father more care than the other children. Dmitri considered himself a great thinker and scientist. He was known as a hardworking and diligent man. However, all the friends and family said that Dmitri was a stubborn man with a difficult character. Dmitri never gave in to anyone. He kept shouting at the people around him and threatening them for making mistakes. People pointed out Dmitri’s mistakes by sending anonymous letters. Dmitri had several hobbies. He loved making leather bags and book covers and was involved in meteorology and physics. He tried to strengthen and innovate Russia’s industry. Dmitri asked the tsar to free Russia from economic and scientific dependence on the West. Neither the emperor nor his colleagues from the university showed understanding for Dmitri.
Dmitri became interested in science while studying at the Faculty of Physics and Mathematics in Saint Petersburg. The faculty graduated with the best grades. He started working as an assistant, doctoral studies and completed his doctorate at the University of Heidelberg. While in Germany, Dmitri submitted a request to the Ministry of Science of Russia to introduce standardized names for measures and weights. 1899 Russia adopts this proposal. Dmitri finds smokeless gunpowder for the Russian army abroad, although the Russian government did not grant him this patent, so the fame goes to other people. Upon his return to St. Petersburg, Mendeleev began working at the University of Organic Chemistry. He wrote the book “Organic Chemistry”. At the Institute of Technology in St. Petersburg, Dmitri managed to “defend” his doctoral dissertation “On the compounds of alcohol and water” in Russian. He became a full professor at that faculty. In the life of all scientists, middle age is always the most fruitful year. In that period of his life, Mendeleev got the idea for the Periodic Table of the Elements. Dealing with the ideal concentration of vodka for the human body, Mendeleev reveals the idea that the mass of an element is directly related to the properties of that element. Dmitri arranges the chemical elements by the mass of the atoms in the table, giving them ordinal numbers. Understand that the ordinal numbers in the table correspond to the atomic numbers of the elements. In 1896 Dmitri M. published the famous “Periodic Law of Chemical Elements” later in science called Mendeleev’s Law.
The story was circulating in scientific circles that Mendeleev dreamed of the Periodic Table of the Elements due to the impossibility to explain how he came up with this idea. His close friends and visitors to his home knew the secret — the Periodic Table of the Elements was inscribed on checkered plates in his bathroom above the bathtub — oily paint and flawless. Because of the tiles, the system is still in the shape of cubes and not, say, in the shape of a circle – a symbol of the atom.
Mendeleev was known for his arbitrariness. He decides to fly in a balloon to better monitor the solar eclipse, the strength and intensity of lightning and the way lightning strikes. He sailed in a balloon from St. Petersburg to Tver, where the balloon fell. This flight was known in Russia and to scientists all over the world. The French Academy of Meteorological Aero-Nautics awards him a diploma “for bravery while flying in a balloon”. Foreign scientists had little appreciation for his work and contribution to science. Russia nominated him three times for the Nobel Prize: 1905, 1906 and 1907. In 1907, the Prize Committee decided to award Mendeleev the Nobel Prize in Chemistry, which he was to share with the Italian S. Canisar. On February 2, 1907, Mendeleev died of pneumonia, so the award was never presented to him. He was buried in the Alley of Writers entitled “Literary Port at the Volkov Cemetery in St. Petersburg. Mendeleev explained his research and scientific achievements in 25 published books. He was an academic professor, chemist, scientist, geologist, innovator, meteorologist and hot air balloon pilot.
