Lothar Meyer curve represents the variation of atomic volume with atomic weight of elements.

Elements present at the maxima (peak) of the curve are highly reactive (mainly alkali metals), so (B) is correct.

Representative elements are not present at the bottom of the curve; transition elements generally occupy lower positions, so (A) is incorrect.

Alkaline earth metals are present on the descending part of the curve, so (D) is correct.

Answer: (B) and (D)
