Question

Answer

In 1869 he published a table of the elements organized by increasing atomic mass. At the same time, he published his own table of the elements organized by increasing atomic mass. Both Mendeleev and Meyer arranged the elements in order of increasing atomic mass

Answer

Arrangement of Elements by Lothar Meyer
Lothar Meyer arranged the elements in order of increasing atomic weight. This arrangement eventually led to the development of the periodic table.

Explanation

Atomic Weight: Atomic weight is the average mass of an atom of an element, taking into account the different isotopes and their relative abundance. Lothar Meyer's arrangement of elements in increasing atomic weight allowed him to observe certain trends and patterns in their properties.

Periodic Table: By arranging the elements in order of increasing atomic weight, Meyer noticed that elements with similar properties appeared at regular intervals. This observation laid the foundation for the development of the periodic table, which was later refined by Dmitri Mendeleev.

Significance: Lothar Meyer's arrangement of elements based on atomic weight was a crucial step towards understanding the relationships between different elements and predicting the properties of undiscovered elements.

Conclusion
In conclusion, Lothar Meyer's arrangement of elements in order of increasing atomic weight played a significant role in the development of the periodic table. This method allowed for the identification of trends and patterns in the properties of elements, leading to a better understanding of the natural order of elements.
