Elementy

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 using pip:

pip install elementy

Usage

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

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
