Dmitri Mendeleev, born in 1834 in Russia, was a pioneering chemist best known for his creation of the periodic table of elements. His periodic table organized elements based on their atomic mass and chemical properties, arranging them into rows and columns that demonstrated recurring patterns and relationships. Mendeleev’s insight into the periodicity of chemical elements allowed him to predict the properties of undiscovered elements and to suggest corrections to existing atomic weights. His work laid the foundation for the modern understanding of the structure of the atom and the organization of the periodic table. Mendeleev’s periodic table has since become one of the most important tools in chemistry, providing a framework for organizing and studying the properties of elements. He died in 1907, leaving behind a legacy of groundbreaking scientific achievement.

Dmitri Mendeleev Quotes

1. “I saw in a dream a table where all the elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper.”
— Dmitri Mendeleev

2. “Work, look for peace and calm in work: You will find it nowhere else. Pleasures flit by – they are only for yourself; work leaves a mark of long-lasting joy, work is for others.”
— Dmitri Mendeleev

3. “Knowing how contented, free, and joyful is life in the world of science, one fervently wishes that many would enter its portals.”
— Dmitri Mendeleev

4. “There is nothing in this world that I fear to say.”
— Dmitri Mendeleev

5. “If all the elements are arranged in the order of their atomic weights, a periodic repetition of properties is obtained. This is expressed by the law of periodicity.”
— Dmitri Mendeleev

6. “No one nor anything can silence me.”
— Dmitri Mendeleev

7. “The elements which are the most widely diffused have small atomic weights.”
— Dmitri Mendeleev

8. “Work, look for peace and calm in work: you will find it nowhere else.”
— Dmitri Mendeleev

9. “The edifice of science not only requires material, but also a plan. Without the material, the plan alone is but a castle in the air-a mere possibility; whilst the material without a plan is but useless matter.”
— Dmitri Mendeleev

10. “It is the function of science to discover the existence of a general reign of order in nature and to find the causes governing this order. And this refers in equal measure to the relations of man – social and political – and to the entire universe as a whole.”
— Dmitri Mendeleev

11. “There exists everywhere a medium in things, determined by equilibrium.”
— Dmitri Mendeleev

12. “The elements, if arranged according to their atomic weights, exhibit an apparent periodicity of properties.”
— Dmitri Mendeleev

13. “No law of nature, however general, has been established all at once; its recognition has always been preceded by many presentiments.”
— Dmitri Mendeleev

14. “When the elements are arranged in vertical columns according to increasing atomic weight, so that the horizontal lines contain analogous elements again according to increasing atomic weight, an arrangement results from which several general conclusions may be drawn.”
— Dmitri Mendeleev

15. “I have achieved an inner freedom.”
— Dmitri Mendeleev

16. “The establishment of a law, moreover, does not take place when the first thought of it takes form, or even when its significance is recognised, but only when it has been confirmed by the results of the experiment.”
— Dmitri Mendeleev

17. “Certain characteristic properties of elements can be foretold from their atomic weights.”
— Dmitri Mendeleev

18. “The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body.”
— Dmitri Mendeleev

19. “I have to talk like this! It’s my job.”
— Dmitri Mendeleev

20. “We must expect the discovery of many as yet unknown elements-for example, elements analogous to aluminum and silicon- whose atomic weight would be between 65 and 75.”
— Dmitri Mendeleev

21. “The most all penetrating spirit before which will open the possibility of tilting not tables, but planets, is the spirit of free human inquiry. Believe only in that.”
— Dmitri Mendeleev
