Periodica.Data

This repository contains data of all chemical elements in the periodic table, wrapped for .NET. It is originally created for usage in the Periodica Windows 10 app and the ElemenTable Windows Desktop app.

Usage

using Bluegrams.Periodica.Data;
// ...
// Load the element data
var table = PeriodicTable.Load();
// Access elements by symbol or atomic number.
Element helium = table["He"];
Element uranium = table[92];
// Access some data for an element
int atomicNumber = helium.AtomicNumber;
int[] shellConfig = helium.ShellConfiguration;
bool radioactive = uranium.Radioactive;
// Output all available data
Debug.WriteLine(uranium.ToString());

The Data

The data of the elements is stored in CSV format in the file Periodica.Data/Data/ElementData.csv. Additionally, the names of the elements are translated to several languages. Currently these are:

• English (default)
• German
• Spanish
• French

All data is parsed using the CsvHelper library.
