Question

which two chemists organized elements based on properties such as how the elements react or whether they are solid or liquid?
lavoisier and mendeleev
döbereiner and newlands
newlands and mendeleev
lavoisier and döbereiner

Explanation:

Antoine Lavoisier was one of the first to classify elements based on their properties (e.g., gases, metals, non - metals). Dmitri Mendeleev organized elements in the periodic table based on properties like reactivity and physical state (solid/liquid/gas). Döbereiner focused on triads (groups of three elements with similar properties) but not as comprehensively as Lavoisier and Mendeleev in terms of the range of properties mentioned. Newlands' Law of Octaves was more about periodicity in properties but not as broad in the property - based organization as Lavoisier and Mendeleev.

Answer:

Lavoisier and Mendeleev
