- An uncharged atom is electrically neutral because electrons and protons have opposite charges of equal sizes. (hawaii.edu)
Solvent3
Chemically4
- Experiments over many years have helped scientists recognize that pure substances include elements, which cannot be broken down, and compounds, which can be broken down chemically into the elements that make them up. (visionlearning.com)
- Compounds have a definite composition and are chemically formed. (visionlearning.com)
- Compounds are chemically made and can only be chemically separated. (visionlearning.com)
- Molecules are formed when 2 or more atoms combine chemically. (infomory.com)
Periodic table2
- Atoms are the smallest parts of elements - pure substances found on the periodic table. (visionlearning.com)
- The content and activity in this topic will work towards building an understanding of the structure of atoms and how elements are organized on the periodic table. (hawaii.edu)
Chemistry4
- Here, we present a high-throughput approach utilizing established computational quantum chemistry methods (CQC) to produce a database of approximate infrared spectra for 958 P-molecules. (frontiersin.org)
- We chose the strongly performing harmonic ωB97X-D/def2-SVPD model chemistry for all molecules and test the more sophisticated and time-consuming GVPT2 anharmonic model chemistry for 250 smaller molecules. (frontiersin.org)

Synthesis3
- 7 In this article, we present our results on the synthesis, crystal structure and anti-ischaemic activity of new cinnamide derivative of (E)-1-{4-[bis(4-methoxyphenyl)methyl]piperazin-1- yl}-3-(4-chlorophenyl)prop-2- en-1-one (5). (scielo.org.za)
- All chemicals, reagents, and solvents for synthesis of the compound were commercially available and used without further purification. (scielo.org.za)
- We undertook the synthesis of structures that were condensates of heterocyclic methyl carbimidates with 2-chlorobenzenesulfonamide and 4-chloropyridine-3-sulfonamide. (springer.com)
Chlorine atom3
- Chlorine atom. (vietdecor.biz)
- This compound has a chlorine atom in its structure linked to the quinoxaline ring (C-5) substituted at the C-2 position with a sulfanilamide moiety. (springer.com)
- The subject of this work was to study the reactions of heterocyclic carbimidates with sulfonamides that have a chlorine atom as a substituent in the ortho position to the sulfonamide group. (springer.com)
