Question about getting the table behind ElementData

Question

I am interested in retrieving the entire table (preferably in text or csv format) that is behind the ElementData function for ALL the elements. The table (or perhaps multiple tables) record(s) many properties (about 75) for each element. So basically I would have a table with about 118 elements that would like something like this:

Element | Atomic Number | Atomic Weight |Property 1 | Property 2 | … |Property n

N | 7 | 14.0067 | Value 1 | Value 2 | … | Value n

… … … … … … …

I know some properties for some elements may not have been measured or relevant but this is okay. Any help would be greatly appreciated. If you know of an outside source that has a comprehensive table, please let me know. THANK YOU!

Answer 1

You may use the Knowledge Representation & Access functions.

As mentioned it may take a while and not all properties lend themselves well to a text representation in a CSV file.

For example, taking a look at "Carbon" shows the issues you will have attempting to save it into CSV. Have a look at the "allotropes" and the "common compound names" properties. The later is a list of 100 items.

EntityValue[Entity["Element", "Carbon"], EntityProperties["Element"], "Dataset"]

However, you can pull them all down into a Dataset and then pick how you intend to save from the extensive list of Importing and Exporting files types that are available.

ds = EntityValue[EntityClass["Element", All], EntityProperties["Element"], "Dataset"]

Hope this helps.

There are likely too many properties (85) for you to make a simple table:

ElementData["Properties"]

{"Abbreviation", "AdiabaticIndex", "AllotropeNames", "AllotropicMultiplicities", "AlternateNames", "AlternateStandardNames", "AtomicMass", "AtomicNumber", "AtomicRadius", "Block", "BoilingPoint", "BrinellHardness", "BulkModulus", "CASNumber", "Color", "CommonCompoundNames", "CovalentRadius", "CriticalPressure", "CriticalTemperature", "CrustAbundance", "CrystalStructure", "CuriePoint", "DecayMode", "Density", "DiscoveryCountries", "DiscoveryYear", "ElectricalConductivity", "ElectricalType", "ElectronAffinity", "ElectronConfiguration", "ElectronConfigurationString", "Electronegativity", "ElectronShellConfiguration", "FusionHeat", "GasAtomicMultiplicities", "Group", "HalfLife", "HumanAbundance", "IconColor", "IonizationEnergies", "IsotopeAbundances", "KnownIsotopes", "LatticeAngles", "LatticeConstants", "Lifetime", "LiquidDensity", "MagneticType", "MassMagneticSusceptibility", "MeltingPoint", "Memberships", "MeteoriteAbundance", "MohsHardness", "MolarMagneticSusceptibility", "MolarVolume", "Name", "NeelPoint", "NeutronCrossSection", "NeutronMassAbsorption", "OceanAbundance", "Period", "Phase", "PoissonRatio", "QuantumNumbers", "Radioactive", "RefractiveIndex", "Resistivity", "Series", "ShearModulus", "SolarAbundance", "SoundSpeed", "SpaceGroupName", "SpaceGroupNumber", "SpecificHeat", "StableIsotopes", "StandardName", "SuperconductingPoint", "ThermalConductivity", "ThermalExpansion", "UniverseAbundance", "Valence", "VanDerWaalsRadius", "VaporizationHeat", "VickersHardness", "VolumeMagneticSusceptibility", "YoungModulus"}

So you'll have to pick out the ones you need.

Try this:

Table[
     ElementData[n, ElementData["Properties"][[j]]], 
{n, 118}, {j, {8,55,15,49}}] // TableForm

to get the atomic number (property 8), name (55), color (15) and boiling point (49).
