The phrase "atomic shell" is correct and usable in written English.
It is typically used in the context of chemistry or physics to refer to the arrangement of electrons around an atom's nucleus.
Example: "In chemistry, understanding the concept of the atomic shell is crucial for predicting how atoms will interact with one another."
Alternatives: "electron shell" or "atomic orbit".
Ideal pyrite has three Fe atoms at 2.26 Å and one S atom at 2.14 Å. Marcasite has a similar first atomic shell structure with S atoms at 2.21 and Fe between 2.23 and 2.25 Å.
The sum of the Bi3+ displacements along the polar ⟨11̅0⟩p direction was calculated, and the ratio of Bi3+ cations displaced in the same direction over all bismuth atoms was evaluated for each atomic shell.
For example, in the mineral ferroselite the first atomic shell surrounding Se has four atoms between 2.34 and 2.5 Å (three Fe atoms and one Se atom, Table IV).
The first atomic shell surrounding Se contains three Fe atoms at 2.25 Å. Attempts to fit S in this shell with and without iron were unsuccessful.
The fourth atomic shell was fit with four Fe atoms at 3.49 Å, which is most similar to the bond distance observed in pyrite.
Helium, the second element in the periodic table, has two electrons, which constitute a filled atomic shell.
The electrons of these metal atoms are in filled atomic shells except for a few electrons that are in unfilled sp-shells.
Atoms can be shown with symbolised atomic shells (Figure 2), which can be separately shaped.
All other types of magnetic behaviors are observed in materials that are at least partially attributed to unpaired electrons in their atomic shells, often in the 3d or 4f shells of each atom.
The third and fourth shells were fit with Se and Fe atoms, respectively, resulting in bond distances consistent with the weighted average for these atomic shells in dzharkenite.
Filled atomic shells with d-orbitals have an important role in covalent bonding.
