Chemical data for all your elements need

Localized, extended periodic table and more in multiple formats

---

Goal

The goal of this project is to facilitate easy to use data regarding chemical subjects such as the periodic table. Any and all contribution to add more data to the project is welcome.

Available data

As of now, this repository contains data for the periodic table in regard to elements. There are also data for elementary particles. The available elements have been translated to a multitude of languages.

Elements

The file named elements contains a series of elements in the following format. The example is in JSON and shows the Hydrogen element.

"number": 1,
"symbol": "H",
"name": "Hydrogen",
"mass": 1.00794,
"cpkHexColor": "FFFFFF",
"electronConfiguration": 1,
"electronNegativity": 2.2,
"radius": 37,
"ionRadius": null,
"vanDelWaalsRadius": 120,
"ionizationEnergy": 1312,
"electronAffinity": -73,
"oxidationStates": [-1, 1],
"standardState": "gas",
"bondingType": "diatomic",
"meltingPoint": 14,
"boilingPoint": 20,
"density": 0.0000899,
"family": "nonmetal",
"yearDiscovered": 1766

quantity	unit	symbol
mass	grams per cubic centimeter	g/cm3
melting / boiling point	kelvin	k
radius	piko meters	pm

Localized elements

Each element has been translated to 30 languages. All of which are available in the elementsLocale file. Each locale is named after the two characters long language code (i.e. 'en' for English). Each localized element is matched to the english word.

"sv": {
  "Hydrogen": "Väte"
}
"tr": {
  "Hydrogen": "Hidrojen"
}

Elementary particles

The file elementaryParticles contain just that, information about elementary particles. The format is as follows:

"proton": {
  "charge": 1,
  "mass": 1007276466812,
  "radius": 0.8775,
  "spin": 0.5,
  "discovered": {
    "year": 1918,
    "name": "Ernest Rutherford"
  }
}

quantity	unit	symbol
mass	unified atomic mass unit	u
spin	-	-
radius	piko meters	pm

Contributing

Any help with the project is more than welcome. If you're unable to add a change yourself, open an issue and let someone else take a look at it.
