Chemical Element Properties =========================== The script *print_atom_elem_props.py* demonstrates how to iterate over the atoms of molecules read from a specified input file and retrieve the following properties associated with the chemical element of each atom: - Atomic weight - IUPAC group - Periodic table period - VdW radius - Covalent radius (bond order=1) - Covalent radius (bond order=2) - Covalent radius (bond order=3) - Allred Rochow electronegativity - Element name - Valence electron count - Is supported chemical element - Is main group element - Is metal - Is transition metal - Is non-metal - Is semi-metal - Is halogen - Is noble gas **Synopsis** :program:`python` *print_atom_elem_props.py* <file> **Code** .. literalinclude:: /downloads/print_atom_elem_props.py :language: python :linenos: :lines: 21- :download:`Download source file</downloads/print_atom_elem_props.py>`
