Mendeleev realized that some elements had not been discovered.
Mendeleev succeeded in creating the periodic table because he organized elements by increasing atomic mass and recognized patterns in their properties, allowing him to predict the existence and characteristics of undiscovered elements. His willingness to leave gaps for unknown elements demonstrated his confidence in the periodic nature of elements, which others had overlooked. Additionally, Mendeleev's approach combined both experimental data and theoretical insights, enabling a more comprehensive understanding of elemental relationships. This innovative thinking set his work apart from that of his contemporaries.
The atomic masses corrected by Mendeleev are those of beryllium, indium, and uranium. Mendeleev was able to accurately predict the properties of these elements based on their corrected atomic masses.

In 1869, he published the greatest of his works, Principles of Chemistry, where he formulated his famous periodic table, translated into many languages ​​and that was a textbook for many years.

Build a car, then try to sell it. If you're successful and become well - known, then you have succeeded. If you don't, you've failed like many others.
Mendeleev. Many others contributed ideas before bu Mendeleev's contribution is considered the most important.
Each 13 state had their own currency. The United States didn't make a legal tender until 1863.
The New Deal was a set of programs carried out after the Great Depression to help the economy and citizens. Many people thought it succeeded in carrying out those terms, while others think it failed.

Dimtrii Mendeleev made the first Periodic Table. dmitry mendeleev
Dimitri Mendeleev is known for several quotations. " Among them are: Pleasures flit by - they are only for yourself; work leaves a mark of long-lasting joy, work is for others," and "There exists everywhere a medium in things, determined by equilibrium".
A lot of people. Orville and Wilbur Wright built the first one that flew and landed safely. The Wright Brothers succeeded where others failed by making a plane that could be controlled, and by learning to fly gliders before they tried flying a powered airplane.
