Dmitri Mendeleev and the Periodic Table

A chemical element discovered after Mendeleev predicted its existence, named after the historical region of Gaul (France).

A prediction about the properties of an undiscovered element made by Mendeleev, based on its position on the periodic table.

The ability of Dmitri Mendeleev's periodic table to predict the existence and properties of undiscovered elements.

The first artificially created element in 1937, named in honor of Dmitri Mendeleev, who predicted its existence.

Element number 101 discovered in 1955, named after Dimitri Mendeleev in recognition of his contributions to the understanding of the periodic system.

Mendeleev's periodic table was unique because it included blank spaces where he predicted undiscovered elements would be, based on their expected properties.

Mendeleev named the undiscovered elements using Sanskrit words like "eka" meaning "one", combined with the name of the element above it in the table. So, the element below aluminum was called "eka-aluminum", which essentially means "one aluminum."

Mendeleev could predict the physical properties of the undiscovered elements, like their atomic weight, density, melting point, etc. by considering their position on the periodic table and how they related to the elements around them.

The blank spaces in Mendeleev's table were not just empty. They were a testament to his scientific insight and predictive power, allowing him to suggest the existence of elements that were yet to be discovered.

Mendeleev's predictions paved the way for future discoveries, validating his periodic table and solidifying his legacy as a visionary scientist.
