Question

what is the drawback of Lother Meyer's atomic volume curve ? just two points.​

Answer 1

Answer:

Lothar Meyer’s Atomic Volume Curve:

Lothar Meyer’s Atomic Volume Curve:Lothar Meyer a German chemist plotted a graph between atomic weight and atomic volume (i.e. atomic weight in solid state/density) and he find out that elements with similar properties occupied the similar positions on the graph. Strong electropositive elements of IA group except Li i.e. Na, K, Rb, Cs etc. occupied the top position on the graph. IIa group elements like Be, Mg, Ca, Sr, Ba etc. occupied the positions on the ascending part of the graph. Inert gases except He occupied the positions on the descending part of the graph. Halogens also occupied the descending part of the graph.

Meyer's classification was supported by a study of various physical properties such as atomic volume, atomic size etc. related with atomic weights with no empirical or logical basis or classification and it is difficult to remember such values.
