The phrase "atomic group" is correct and usable in written English.
It can be used in scientific contexts, particularly in chemistry or physics, to refer to a group of atoms that behave as a single unit.
Example: "In the molecular structure, the atomic group plays a crucial role in determining the compound's properties."
Alternatives: "molecular group" or "atomic cluster".
A new dislocation model for the {332} twinning mechanism is proposed whereby that after a pair of stacked twinning dislocations move, shuffling of an atomic group consisting of three atoms occurs, forming one elementary twinned layer of four {332} planes.
If X is large, the difference between the two atomic sizes is large, and the two dissimilar atoms combined more tightly together and the atomic group is more stable.
Peroxy acid, also called Peracid, any of a class of chemical compounds in which the atomic group −O−O−H replaces the −O−H group of an oxy acid (a compound in which a hydrogen atom is attached to an oxygen atom by a covalent bond that is easily broken, producing an anion and a hydrogen ion).
The atomic group –OH is the Hp-π donor in amino acids Ser, Thr, and Tyr.
The atomic group –OH is the Hp-π donor in Ser, Thr, and Tyr.
The atomic group > NH or –NH2 is the Hp-π donor of Asn, Gln, Lys, Arg, Trp, and His.
The atoms or atomic groups exposed in crystal surface were used to analyze the relationship between structure and morphology.
Compared to the surrounding faces, the needle tip faces have a large number of polar atoms or atomic groups.
The similar significant properties may exist in the edge-chemistry-modified silicene nanoribbons, so we choose H, F, OH, and O atoms or atomic groups for investigation.
In this paper, we report the simulations of the geometry structures and electronic properties of the 8-ZSiNRs (with eight zigzag armchair chains) with edge-chemistry modifications by H, F, OH, and O atoms or atomic groups.
In proteins the Hp-π interaction donors are the polar hydrogen atoms in atomic groups [12 16] –NH2, >NH, –OH, –SH, and C6H5OH, which exist in amino acids Ser, Thr, Tyr, Trp, Cys, His, Asn, Gln, Lys, and Arg, while the acceptors are the aromatic amino acids, Phe, Tyr, Trp, and His [19, 20].
