ХИМИЯ! СРОЧНО! Как Менделеев определил массу атомов?

Answer 1

How Did Mendeleev Determine the Mass of Atoms?

Dmitri Mendeleev, a Russian chemist, is best known for his development of the periodic table of elements. In order to determine the mass of atoms, Mendeleev relied on experimental data and observed patterns in the properties of elements.

Mendeleev's approach was based on the concept of atomic weight, which is the average mass of an element's atoms. He recognized that elements could be grouped together based on their similar chemical properties and arranged them in a table according to increasing atomic weight.

To determine the atomic weight of an element, Mendeleev considered the known properties of elements and their compounds. He analyzed the ratios of elements in various compounds and compared them to the ratios predicted by their atomic weights. By doing so, he was able to identify inconsistencies and make adjustments to the atomic weights of certain elements.

Mendeleev's periodic table allowed him to predict the existence and properties of undiscovered elements based on the patterns he observed. He left gaps in the table for elements that were yet to be discovered, and he accurately predicted their properties and atomic weights.

It's important to note that Mendeleev's determination of atomic weights was based on the available data and scientific understanding of his time. Over the years, advancements in technology and further research have led to more accurate measurements of atomic weights.
