* Fix unit of molar heat * Adjust command line parser and help messages The adjustmenst reflect how the code as is actually works and the extended help message give actual examples of how to use the command. * Clarify help message * Make command executable * Add option to quit adding properties * Refactor output to use functionality from argparse Default behavior is now more robust for output. Changed write functions to use less of global state. * Parameterize help message fors default output file name * Improve prompt to quit interactive loop * Add example with properties and interactive * Remove debug cruft * Refactor write functions to not use global variables * Skip already selected in interactive phase given by properites * Improve help message * Refactor logic for output in the default case USe the functionality provided by argparse for default values of an optional command line argument. In this case --output. * Restructure code by moving already defined functions up * Refactor structure of code to use functions This is s step towards further simplification of each step. * Refactor use of keys and clear screen for interactive use only * Add the main guard * Use argparse hook to parse comma separated properties This provides a list of arguments directly. Find the set intersection and difference to filter out correctly named properties. Structure the code so as to keep the terminal output separate. * Refactor interactive paring to us local functions * Use result provided by default_input * Use pylint to clean up * Improve docstrings * Format help message * Refactor name and replace with namedtuple
Periodic-Table-JSON
A json of the entire periodic table. Feel free to use it in your projects.
Temperatures such as boiling points and melting points are given in Kelvin. Densities are given in g/l for gases and g/cm³ for solids and liquids and molar heat in J/(mol*K). Information that is missing is represented as null. Some elements may have an image link to their spectral bands.
All elements have a three sentence summary from Wikipedia.
Electron configuration is given as a string, with each orbital separated by a space. Electron configuration semantic is given as a string, this is the short-hand version of the electron configuration. Elements with a semantic electron configuration marked with a "*" mean that the electron configuration has not yet been confirmed. Electron shells are given as an array, the first item is the number of electrons in the first shell, the 2nd item is the number of electrons in the second shell, and so on.
Both ionization energy and first electron affinities are given as the energy required to detach an electron from the anion. Ionization energies are given as an array for successive ionization energy.
A link to the source where the information was from is provided in each element under the key "source".
A link to image Bohr model (of the atom) is available under "bohr_model_image" key.
A link to 3d-image of Bohr model available under "bohr_model_3d" key, file obtained from google with .glb extension and these 3d models can easily display on web using google model-viewer script

Additional Formats
Besides the original JSON file PeriodicTableJSON.json, the data is provided in the following additional formats:
-
As a lookup table for easy indexing in
periodic-table-lookup.json. -
As a CSV file (one row per element and one column per property, where some subfields are flattened to strings) in
periodicTableCSV.csv.
These files are generated from the original data via scripts in the directory scripts.
