The phrase "atoms were introduced" is correct and usable in written English.
It can be used in contexts discussing scientific concepts, theories, or historical developments related to atomic theory or chemistry.
Example: "In the early 20th century, atoms were introduced as fundamental building blocks of matter, revolutionizing our understanding of chemistry."
Alternatives: "atoms were presented" or "atoms were brought forth".
Additionally, to study the effect of halogenation, fluorine and chlorine atoms were introduced in terms of microscale and mesoscale molecular engineering.
The results confirmed that nitrogen atoms were introduced into the GO structure, which improved the conductivity of the basal plane of nGO.
Hydrogen atoms were introduced to all structures by appropriate rigid body constraints (AFIX 23, AFIX 43 or AFIX 137) with temperature factors Uiso(H) equal to 1.2Ueq(C) for aromatic and methylene hydrogen atoms or 1.5Ueq(C) for methyl hydrogen atoms.
Virtual interaction sites of all hydrogen atoms were introduced, thereby removing all internal vibrational degrees of freedom.
At the final steps of refinement restrained anisotropic temperature factors for the protein atoms were introduced and this step reduced Rfactor and Rfree by 2.4% and 1.5% respectively.
To generate the derivative compounds, halogen atoms were introduced into 4-thiazolidinone compounds that contained carboxylic acid moieties of phenoxy-acetic acid, 5-vinyl-furan-2-yl -benzoicc acid or (5-vinyl-furan-2-yl -benzoiczoic acid.
The structure of benzene as a six-membered ring of carbon atoms was introduced by the German chemist F.A. Kekule in 1865.
Hyperbranched polymers, in which boron atoms are introduced in the form of borates, exhibit superior performance and have more applicability.
In this way, Ag atoms are introduced into the graphene lattice substitutionally via covalent bonding with carbon atoms.
First-principle calculations using quantum-mechanical density functional theory are carried out to study nitrogen incorporation in amorphous carbon, in which the structural models from liquid quench containing 64 atoms are introduced.
