Introduction

If you are a chemistry teacher or student, chances are that you are going to do Z_eff and S calculations based on Slater’s Rules or on Clementi *et al* screening constants. Probably while teaching/learning periodic trends.

This simple project automates these calculations returning them as tables (Pandas DataFrames) so that one can easily plot the data or manipulate them. Indeed, there are plot functions that can do graphs providing a convenient visualization functionality for classes.

Installation

Just clone or download this repo. This is not a package (yet, maybe someday :-))

Usage

Look at some examples at the tutorial available as a Jupyter notebook.

Under the hood - Requirements

This project relies heavily on mendeleev, pandas and matplotlib packages so these must be installed. Check the requirements.txt file for requirements and feel free to use it to create a virtual environment.
