The relation between the atomic Volume relations of solids. volumes and the atomic weights of the solid elements exhibits the periodicity which generally characterizes the elements.

The equivalent and the density being known, we may calculate the atomic volume.

In elements that have not been weighed in the gaseous state, as C, the evidence of atomic volume is not direct, but we will assume it.

In the case of elements the two are usually identical, i.e. with the few whose vapor density is known; but this is not always true, and it leads to interesting conclusions regarding atomic volume.

Atomic Volume.—As is peculiar in that its atomic volume, so far as the volume can be determined, is only half that of the H atom.
