The positions and trajectories of some simple particles cannot be well known. To have a well-defined position a particle must contain enough of the right sort of quarks to unambiguously establish its spatial orientation. But some of the models that we have discussed cannot satisfy this requirement so their positions cannot be assigned without making further assumptions. For example we cannot state the position of a solitary photon. And this uncertain quality can be observed when Young's experiment is performed at low light levels.

One common way of dealing with this issue to to assume that a particle has been absorbed by an atom that is well defined. Then both particles are supposedly in the same place. Another possibility is to conjecture additional fields or excitations that align a particle's orientation. Such presumptions are codified in various three-dimensional arrangements that assign quarks to sub-orbital events by convention. These structures are called sub-atomic particle models. See the following links for more detail. When atoms and sub-atomic particles are considered together, they are collectively called atomic particles.
