Install package using:\n   ```SSH\n   npm i @kykal/chemistry\n   ```\n2. You can import the elements to your file in two ways:\n   1. If you will use a certain amount of elements, for example:\n   ```JS\n   const { helium, argon, ..., uranium } = require('@kykal/chemistry');\n   \n   console.log( helium.discovered.by );\n   //Output: Pierre-Jules-Cesar Janssen\n   ```\n   2. If you will use all elements: \u003cbr\u003e\n   **Note:** to make it easier for users, the index 0 is *null*. This way you can call the element using its atomic number. ;)\n   ```JS\n   const { element } = require('@kykal/chemistry'); //Import all elements in an array\n\n   console.log( element[1].melting_point ); //Hydrogen\n   //Output: { kelvin: 13.81, celsius: -259.34, fahrenheit: -434.81 }\n   ```\n\n# References\nAll this information was gathered thanks to:\n- National Center for Biotechnology Information (2021).
