Which German chemist was the first to show a graphical representation of the periodicity of an atomic volume plotted against atomic weight?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Lothar Meyer.
Lothar Meyer, a German chemist, constructed a graph correlating atomic weight with atomic volume. Elements with analogous characteristics tended to cluster together on this graph. Notably, highly electropositive elements, such as Sodium, Potassium, Rubidium, and others, predominantly occupied the uppermost positions on the chart, with the exception of Lithium.
