# Elementy

[![Documentation Status](https://readthedocs.org/projects/elementy/badge/?version=latest)](https://elementy.readthedocs.io/en/latest/?badge=latest)

This package provides an interface to a variety of different data on elements of
the periodic table.

## Installation

The metallurgy package can be installed from
[pypi](https://pypi.org/project/elementy/) using pip:

``pip install elementy``

## Usage

Access to elemental data is easily obtained by creating an instance of the
periodic table:

```python
from elementy import PeriodicTable

periodic_table = PeriodicTable()

>>> periodic_table.elements["Cu"]["mass"]
63.546

>>> periodic_table.elements["Cu"]["valence_electrons"]
11

>>> periodic_table.elements["Cu"]["melting_temperature"]
1357.77
```
