That would be Dmitri Mendeleev.
a classification
For a detailed answer see the link below.
The most detailed level of classification is species. Organisms within the same species share similar characteristics and can reproduce with one another to produce fertile offspring. This classification is followed by genus, family, order, class, phylum, and kingdom.
A detailed list of identifying characteristics that includes scientific names is called a taxonomic key. It is used to aid in the identification of organisms by providing a systematic way to determine their classification based on specific characteristics.
Well Mendeleev constructed the first well detailed periodic table based on the atomic masses of each element. The elements were arranged in an increasing order of their atomic masses. His principle was that the increasing atomic mass determines the periodic properties of each element. This eventually led him to predict new elements. But his table had some flaws one of them being that hydrogen had same characteristics as that of alkali metals and halogens. Another being that the isotopes had no place in the periodic table.
To create a detailed chart for your chemistry project using the periodic table of elements, you can organize the elements by their atomic number, symbol, and properties. You can also include information such as atomic mass, electron configuration, and group and period numbers. Utilize a software program or online tool to help you design and format the chart effectively.

Each row of elements on the periodic table is called (ironically) a period! If you want to know the specific elements, try using a search engine to look it up, as there are over 100 elements and the list is too extensive to write out here (when it's already detailed far better in other sites).
Different number of elements: Each periodic table contains the same elements, but the number of elements included may vary depending on the table's design and purpose. Arrangement: Various periodic tables may organize elements differently, such as by atomic number, electron configuration, or properties. Color-coding: Some periodic tables use different color-coding schemes to highlight specific trends or groupings of elements. Additional information: Some periodic tables may include extra information alongside the basic elements, such as isotopes, electron affinities, or more detailed atomic properties.
The first periodic table was constructed by Dmitri Mendeleev in 1869, who organized known elements by increasing atomic mass and grouped them by similar chemical properties. Mendeleev's table predicted the existence of undiscovered elements, leaving gaps for them. The modern periodic table has evolved to arrange elements by atomic number rather than atomic mass, reflecting a better understanding of atomic structure and electron configuration. Additionally, it includes newly discovered elements and provides more detailed information about each element's properties.
One limitation of Linnaeus' classification system is that it is based on physical characteristics alone, which may not always accurately reflect evolutionary relationships. It does not take into account genetic information, which can provide a more detailed and accurate understanding of relationships between organisms.
