Dmitri Mendeleev's main contribution to science was his development of the periodic table of elements. In 1869, Mendeleev organized the elements based on their atomic mass and properties, creating a system that predicted the existence and properties of elements that had not yet been discovered. His work laid the foundation for our modern understanding of chemistry.
Alfred Nobel's contribution to science was the invention of dynamite, a safer form of explosive compared to the unstable nitroglycerin. This invention revolutionized the construction and mining industries. Dynamite is related to chemistry as it involves the chemical reaction of nitroglycerin with an absorbent material to create a more stable and controllable explosive.
His atomic theory. He was the one who thought that there were atoms in everything.
Dmitri Mendeleev's major contribution was the development of the periodic table of elements. This organization of elements based on their atomic number and properties revolutionized chemistry and laid the foundation for modern chemistry and physics. His work has had a profound impact on scientific understanding and continues to influence research and education today.
Henry Cecil Ransom McBay was a prominent African American chemist who made significant contributions to the field of chemistry, particularly in the study of black carbon and its properties. He also played a key role in advancing science education and promoting diversity in the field of chemistry.

Charles Darwin was a naturalist. His major contribution to science was the Theory of Evolution.
First African American woman licensed pilot
her best contribution was science
he told that science is science and sciance cannot be science if sceince if science is not science and if science did not come from science the science will not be science
it is discovered
