    en.wikipedia.org/wiki/Category:Cyclosilicates

    Cyclosilicates are ring silicates which contain rings of linked SiO 4 tetrahedra. The Si:O ratio is 1:3. Three configurations can occur: the Si 3 O 9, ...

    With two shared oxides bound to each silicon, cyclic or polymeric structures can result. The cyclic metasilicate ring Si 6 O 12− 18 is a hexamer of SiO 3 2-. Polymeric silicate anions of can exist also as long chains. In single-chain silicates, which are a type of inosilicate, tetrahedra link to

    en.wikipedia.org/wiki/Cyclic_compound

    A heterocyclic compound is a cyclic compound that has atoms of at least two different elements as members of its ring(s). [5] Cyclic compounds that have both carbon and non-carbon atoms present are heterocyclic carbon compounds, and the name refers to inorganic cyclic compounds as well (e.g., siloxanes, which contain only silicon and oxygen in ...

    en.wikipedia.org/wiki/Heterocyclic_compound

    A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). [1] Heterocyclic organic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of organic heterocycles .

    en.wikipedia.org/wiki/Silicon_compounds

    Soro-silicates, involving discrete double or triple tetrahedral units, are quite rare: metasilicates involving cyclic [(SiO n 3)] 2n− units of corner-abutting tetrahedra forming a polygonal ring are also known. [15] Chain metasilicates, {SiO 2− 3} ∞, form by corner-sharing of an indefinite chain of linked SiO tetrahedra. Many differences ...

    A nutrition label will “give you insight into the overall composition of the food,” including preservatives and flavor enhancers that are fine to eat, but not very nutritious, Palinski-Wade says.

  8. Phenyl group - Wikipedia

    en.wikipedia.org/wiki/Phenyl_group

    In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph (archaically φ) or Ø. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a ...

    en.wikipedia.org/wiki/Beryl

    The word beryl – Middle English: beril – is borrowed, via Old French: beryl and Latin: beryllus, from Ancient Greek βήρυλλος bḗryllos, which referred to a 'precious blue-green color-of-sea-water stone'; [2] from Prakrit veruḷiya, veḷuriya 'beryl' [8] [a] which is ultimately of Dravidian origin, maybe from the name of Belur or ...
