The List of data references for chemical elements is divided into datasheets that give values for many properties of the elements, together with various references. Each datasheet is sequenced by atomic number .

Oxford, Cambridge and RSA Examinations [2] (OCR) is an examination board which sets examinations and awards qualifications (including GCSEs and A-levels). It is one of England, Wales and Northern Ireland's five main examination boards. OCR is based in Cambridge, with an office in Bourn, Coventry.
Chemical structures are traditionally represented using lines indicating chemical bonds between atoms and drawn on paper (2D structural formulae).While these are ideal visual representations for the chemist, they are unsuitable for computational use and especially for search and storage.
The Chemical Database Service [1] is an EPSRC-funded mid-range facility [2] that provides UK academic institutions with access to a number of chemical databases. [3] [4] It has been hosted by the Royal Society of Chemistry since 2013, before which it was hosted by Daresbury Laboratory (part of the Science and Technology Facilities Council).
ChemMantis, [14] the Chemistry Markup And Nomenclature Transformation Integrated System uses algorithms to identify and extract chemical names from documents and web pages and converts the chemical names to chemical structures using name-to-structure conversion algorithms and dictionary look-ups in the ChemSpider database. The result is an ...
The data below tabulates standard electrode potentials (E°), in volts relative to the standard hydrogen electrode (SHE), at: Temperature 298.15 K (25.00 °C; 77.00 °F); Effective concentration (activity) 1 mol/L for each aqueous or amalgamated (mercury-alloyed) species; Unit activity for each solvent and pure solid or liquid species; and
SDF is one of a family of chemical-data file formats developed by MDL; it is intended especially for structural information. "SDF" stands for structure-data format, and SDF files actually wrap the molfile (MDL Molfile) format. Multiple records are delimited by lines consisting of four dollar signs ($$$$). A key feature of this format is its ...
