The main difference is atoms that which are channelled through the diffusing process where the atoms stick to the molecular structure of a material this only happens in interstitial diffusion where in vacancy diffusion the atoms reppelled away hence the word vacancy.
(a) Compare interstitial and vacancy atomic mechanisms for diffusion. (b) Cite two reasons why interstitial diffusion is normally more rapid than vacancy diffusion. Solution (a) With vacancy diffusion, atomic motion is from one lattice site to an adjacent vacancy. Self-diffusion and the diffusion of substitutional impurities proceed via this mechanism. On the other hand, atomic motion is from interstitial site to adjacent interstitial site for the interstitial diffusion mechanism. (b) Interstitial diffusion is normally more rapid than vacancy diffusion because: (1) interstitial atoms, being smaller, are more mobile; and (2) the probability of an empty adjacent interstitial site is greater than for a vacancy adjacent to a host (or substitutional impurity) atom.
the simplest of the point defects is a vacancy or vacant lattice site ,one normally occupied from which atom is missing is called vacancy a self-interstitial is an atom from a crystal that is crowded into an interstitial site , a small void space that under ordinary circumstances is not occupied.
In this case a cation-vacancy defect is created.
A common type of point defect that occurs in a crystal of zinc sulphide is a vacancy defect. In this defect, an atom is missing from its lattice position, creating a gap or a vacancy in the crystal structure.
There are 5 elements that have for letters: 10 Ne neon, 26 Fe iron, 30 Zn zinc, 79 Au gold and 82 PB lead. Neon is the only one, that is NOT a solid at room temperature here on planet earth. It also makes neat beer signs and vacancy indications.

In solids one could find place where the atom should be, but missing. Such places are called vacancies. With increasing of temperature neighbor atom could jump on the vacancy, so vacancy will disappear in place where it was, but appear in the place, where atom was. This process is stochastic, so vacancy will move in random direction. Density of vacancies will change in time with accordance to diffusion equation.
I think it would be a point defect because a vacancy in the lattice structure would allow another atom to take the place of the vacancy.

The word 'vacancy' can encompass more than the word 'jobs'. While the word 'vacancy' could mean that a company has a job available, it could also be used to refer to an open hotel room or apartment.
The quality or state of being vacant; emptiness; hence, freedom from employment; intermission; leisure; idleness; listlessness., That which is vacant., Empty space; vacuity; vacuum., An open or unoccupied space between bodies or things; an interruption of continuity; chasm; gap; as, a vacancy between buildings; a vacancy between sentences or thoughts., Unemployed time; interval of leisure; time of intermission; vacation., A place or post unfilled; an unoccupied office; as, a vacancy in the senate, in a school, etc.
I wanted to stay at a motel, but the one I went to didn't have a vacancy.
The word "vacancy" is a noun.
job vacancy
Select Vacancy was created in 2006.
the root word for vacancy is vacant
