The names of the scientists, Newlands, Mendeleev, and Meyer are associated with the development of A. atomic structure B. metallurgy C. periodic table of contents D. discovery of elements

The correct answer is C. periodic table of contents.

Newlands, Mendeleev, and Meyer were all chemists who developed the periodic table of elements. The periodic table is a tabular arrangement of the chemical elements, organized on the basis of their atomic number, electron configuration, and recurring chemical properties.

Newlands was the first to propose a periodic table of elements, in 1864. He arranged the elements in order of increasing atomic weight, and found that every eighth element had similar properties. This led him to propose the law of octaves, which stated that the properties of the elements repeat every eighth element.

Mendeleev was the first to develop a truly periodic table of elements, in 1869. He arranged the elements in order of increasing atomic weight, and grouped them into columns based on their chemical properties. This allowed him to predict the properties of elements that had not yet been discovered.

Meyer was also working on a periodic table of elements at the same time as Mendeleev. He arranged the elements in order of increasing atomic weight, and grouped them into columns based on their chemical properties. However, his table was not as accurate as Mendeleev’s table.

The work of Newlands, Mendeleev, and Meyer led to the development of the modern periodic table of elements, which is one of the most important tools in chemistry.
