Russian chemist Dmitri Ivanovich Mendeleyev.
Dmitri Mendeleyev
Dmitri Mendeleev was from Russia. He was a Russian chemist who is best known for creating the periodic table of elements.
Dmitri Mendeleev was the Russian chemist who developed the periodic table of elements. He accomplished most of his work during the 1860s. In 1869, he invented a method of arranging the elements that were known at that time in order of their atomic weights.
The periodic table
The element named after Dmitri Mendeleyev is mendelevium, with the atomic number 101. Mendelevium is a synthetic element that was first synthesized in 1955.

Yes, Dmitri Mendeleyev published his periodic law of elements in 1869. He presented it in a paper and later expanded upon it in his book, "Principles of Chemistry." Mendeleyev's periodic table organized elements by increasing atomic mass and grouped them by similar chemical properties, which laid the foundation for modern chemistry. His work significantly advanced the understanding of elemental relationships and periodicity.
I assume you know that Dmitri Mendeleyev was the man that discovered the periodic table and left spaces for future findings of elements. He also has an element names after him. He wrote a book. He is a great guy.
The Russian Chemist, Dmitri Ivanovich Mendeleyev, founded the periodic table. Mendeleyev was the first person to show the similarities and trends in the properties of chemical elements, and he was acknowledged 50 years later when the 101st element was named after him, mendelevium.
