Question

Lothar Meyer used the physical property such as_________to construct a plot showing similarities among particular sets of elements.
(i) atomic volume (ii) meting point
(iii) boiling point
A. `(i)`
B. `(ii),(iii)`
C. `(i),(ii)`
D. `(i),(ii),(iii)`

Answer 1

Correct Answer - D
Lothar Meyer reported that when physical properties such as atomic volume, melting point boiling point, etc.., were plotted against atomic weight, a periodically repeating curve was obtained in each case.
Unlike Newlands, Lothar Meyer observed a change in the length of that repeating pattern.
