    Periodic Table

    This package is a wrapper for a dataset of periodic elements. These elements were taken from a modified Penn State CS class CSV file, transformed into JSON, and then wrapped in some pretty JavaScript accessors.

    npm install periodic-table

    Usage

    var pt = require('periodic-table');
     
    // entire dataset
    var allElements = pt.all();
     
    // single elements by name
    var he = pt.elements.Helium;
     
    // single elements by symbol
    var he = pt.symbols.He;
     
    // single elements by atomic number
    var he = pt.numbers[2];
     
    var util = require('periodic-table/util');
     
    // atomic mass of molecule
    // atomicMass("[Element][Number] [Element][Number] ...")
    // parenthesis around elements not supported..yet
    var waterMass = util.atomicMass("H2 O");
    var organicMass = util.atomicMass("C12 H22 O11");

    Is any table information wrong? Does some field need to be added or better formatted? Is there a more reliable source of information to work with? Open an issue or be even cooler and open a pull-request.
