Chemical Structure Description A chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. The community structure of microbes that were able to use added compounds was evaluated using stable isotope probing (DNA-SIP) combined with qPCR and Illumina sequencing. Molecular structure and chemical compounds. Geometric and polygonal abstract background." Some compounds regarded as chemically identical may have varying amounts of heavy or light isotopes of the constituent elements, which will make the ratio of elements by mass vary slightly. The structure of CH 4, with four hydrogen atoms arranged around a central carbon atom as shown in Figure \(\PageIndex{3}\), is tetrahedral: the hydrogen atoms are positioned at every other vertex of a cube.
