GENERAL KNOWLEDGE

Detailed explanation-1: -Detailed Solution. The correct answer is periodic table of contents. They are associated with the development of the periodic table of elements.

Detailed explanation-2: -Several scientists worked over almost a century to assemble the elements into this format. Among the scientists who worked to created a table of the elements were, from left, Antoine Lavoisier, Johann Wolfang Döbereiner, John Newlands and Henry Moseley.

Detailed explanation-3: -John Newlands, Lothar Meyer, and Dmitri Mendeleev are three chemists who contributed to the development of one of the most ubiquitous structures in chemistry. These three people came from different countries. Newlands was British, Meyer was German, and Mendeleev was Russian.

Detailed explanation-4: -Mendeleev created the first periodic table and was shortly followed by Meyer. They both arranged the elements by their mass and proposed that certain properties periodically reoccur. Meyer formed his periodic law based on the atomic volume or molar volume, which is the atomic mass divided by the density in solid form.

Detailed explanation-5: -In 1864, Julius Lothar Meyer, a German chemist, organized the elements by atomic mass and grouped them according to their chemical properties. Later that decade, Dmitri Mendeleev, a Russian chemist, organized all the known elements according to similar properties.
