# Elementy
[](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
```
### List of data types

are `None` due to lack of experimental data available.
