Periodic Table

Data about chemical elements arranged in JSON format. The module also contains a Element class for convenient access to unit conversion of atomic properties (see example below).

Installation

The package can be installed from NPM as follow:

npm install @exabyte-io/periodic-table.js

Usage

import {PERIODIC_TABLE, ChemicalElement} from "@exabyte-io/periodic-table.js";

console.log(PERIODIC_TABLE.H);

const li = new ChemicalElement("Li");
console.log(li.atomicRadiusIn("bohr"));

Atomic Properties

• name: element name
• symbol: element symbol
• atomic_number: atomic number
• atomic_mass: atomic mass in amu
• atomic_radius_pm: empirical atomic radius in pm by Slater (doi: 10.1063/1.1725697)
• covalent_radius_pm: covalent radius "2008 values" (doi: 10.1039/b801115j)
• van_der_Waal_radius_pm: van der Waals radius (doi: 10.1021/jp8111556, 10.1021/j100785a001)
