detailed solution

Correct option is D

"atomic volume  of an element is not the volume of an atom of that element" is the incorrect statement regarding Lother Meyer curve.

When the elements are organized in order of increasing atomic mass, Lother Meyer's curve states that particular sets of attributes return regularly. "An element's atomic volume can vary.
Consequently, the volume of an atom in an element is not the same as its atomic volume.

Atomic volume is calculated as (atomic weight/density) which is not atomic volume in true

sense $\left(V_{\text{atom }}=\frac{4}{3}\pi r^3\right)$.
