Question

Which two chemists organized elements based on properties such as how the elements react or whether they are solid or liquid

Answer 1

Doberiner and lavoiser

Answer 2

Antoine Lavoisier and Johann Döbereiner

Step-by-step explanation:

One of the very first attempt to classify the elements was made in 1789 by Antoine Lavoisier who grouped all the elements based on their properties into whether they are gases, metals or non metals and earths metals.

Johann Döbereiner in 1829, recognised triads of elements with similar chemical properties and showed that the properties of the element that is in the middle of other two elements can be predicted from the properties of the other two.
