Father of Periodic Table : The periodic table is a table of elements arranged according to their atomic number, electron configuration, and chemical properties. The Russian scientist Dmitri Mendeleev is often credited as the “father of the periodic table” because of his pioneering work in the development of this important tool for understanding the properties of elements.

In 1869, Mendeleev published a periodic table that organized the known elements according to their atomic weight and chemical properties, and he correctly predicted the existence and properties of several elements that had not yet been discovered at the time. Mendeleev’s periodic table was a major breakthrough in the field of chemistry and has had a lasting impact on the way we understand the properties of elements and their relationships to one another.
