Atomic spacing

This space is extremely large compared to the size of the atomic nucleus, and is related to the chemical bonds which bind atoms together.

In ordered solids, the atomic spacing between two bonded atoms is generally around a few ångströms (Å), which is on the order of 10−10 meters (see Lattice constant).

However, in very low density gases (for example, in outer space) the average distance between atoms can be as large as a meter.

In this case, the atomic spacing is not referring to bond length.

The atomic spacing of crystalline structures is usually determined by passing an electromagnetic wave of known frequency through the material, and using the laws of diffraction to determine its atomic spacing.

In this case, the average bond length is a common way of expressing the distance between its atoms.
