What was Mendeleevs proposal?
Dmitri Mendeleev was a Russian chemist who proposed the Periodic Law. He published the first periodic table of the chemical elements in 1869, based on the increasing atomic masses of the different elements.
Why did scientists try to improve Mendeleevs table?
Scientists tried to improve Mendeleev's periodic table to account for the discovery of new elements, better organize elements based on their properties, and to address inconsistencies in the original table. This led to the development of the modern periodic table with elements arranged in increasing atomic number and grouped based on similarities in chemical properties.
Is soap still used today?
Yes, soap is still widely used today for personal hygiene, cleaning, and killing germs. It is a crucial tool in preventing the spread of diseases and maintaining good hygiene practices.
How could Mendeleevs table be used to predict the properties of elements that had not been discovered?
Mendeleev's periodic table allowed for the prediction of the properties of unknown elements by identifying gaps in the table where elements had not yet been discovered. By examining the properties of neighboring elements, Mendeleev was able to predict the properties of the missing elements and suggest their existence. His periodic table provided a framework for organizing elements based on their atomic mass and chemical properties, which allowed for the accurate prediction of the properties of undiscovered elements.
Is Alexander Flemings discovery still used today?
Yes, Alexander Fleming's discovery of penicillin, the first antibiotic, is still widely used today to treat bacterial infections. It revolutionized medicine and has saved countless lives since its discovery in 1928.
How did later chemists change Mendeleevs periodic table?
They used atomic number instead of Atomic Mass to organize the elements
Is a bullhook still used today?
