The phrase "atoms are at" is correct and usable in written English.
It can be used when discussing the location or position of atoms in a scientific context, such as chemistry or physics.
Example: "In this experiment, we will observe where atoms are at different temperatures to understand their behavior."
Alternatives: "atoms are located at" or "atoms exist at".
In the very cold space between the stars, the interstellar hydrogen atoms are at a state of lowest possible energy.
At normal ambient temperatures very little ion hopping takes place, since the atoms are at relatively low energy states.
Metamaterials are artificially structured materials composed of the building blocks of which size and spacing of atoms are at deep sub-wavelength scale.
From this figure, it can be seen that Zn (or Cd) sits at the center of the cubic unit cell while the rare earth atoms are at the corners.
While xenon atoms are at their ground energy state, they repel each other and will not form a bond.
This is especially true in the case of carbon nanotubes, where all constituent atoms are at the surface.
Where binding of atoms is at uniform electron-dynamics, a graphitic structure evolves following by different modifications into other carbon phases depending on the orientation of electron states with respect to centre of inner part of atom known as nucleus.
The difference of the burial levels of two contacting atoms is at most one.
The RIGU restraints require that the relative motion of bonded atoms is at right angles to the bond joining them.
Close inspection of the atomic displacement ellipsoids in Fig. 1 ▶(a) shows that the assumption that the relative motion of the H atoms is at right angles to the bonds holds well, even for the unrestrained refinement.
It should be noted that the real speed of motion of the atoms is at least the apparent monitored rate of migration, since we are limited by the speed of the camera and there could be more steps at intermediate times between frame captures.
