Question

Following Lothar Meyer, one acclaimed scientist worked hard to make a complete and universally recognized system for the elements. Who was this and what year did he do this?

Answer 1

Julius Lothar Meyer and Dmitri Mendeleev both contributed to the development of the periodic table. While Meyer organized the elements based on atomic mass and chemical properties, it was Mendeleev who created the modern periodic table and made key predictions for undiscovered elements.

Step-by-step explanation:

Julius Lothar Meyer, a German chemist, worked hard to make a complete and universally recognized system for the elements. In 1864, Meyer organized the elements by atomic mass and grouped them according to their chemical properties. However, it was Dmitri Mendeleev, a Russian chemist, who is usually credited with the origin of the modern periodic table. Mendeleev published his periodic table in 1869, which gained wide acceptance in the scientific community. His table included predictions for undiscovered elements, which were later confirmed, further supporting his work.
