"""List of all chemical elements, with some of their characteristics.

V.2.0 by leonardo maffi, July 23 2006.

NOTES:
- Some English names are in two forms divided by a comma.
- Temperatures are in C degrees
- The density is in g/dm^3 at 20 C degrees.
- Electronegativity is determined with the Pauling method.
- Unknown, not applicable, or problematic values are missing in the table (like
  Phosphorus melting_point/ boiling_point, that are variable according to its color).
- For more information see: http://en.wikipedia.org/wiki/List_of_elements_by_atomic_number
- Radiactive elements without stable nuclei have a value that indicates the mass number of
  the longest-lived isotope of the element or characteristic isotopic composition.
- Field nome is the Italian name


FIELDS (and their types):
- symbol (str)
- name (list of str)
- atomic_number (int)
- atomic_mass (float)
- group (int)
- period (int)
- pauling_electronegativity (float)
- nome (str)
- density (float)
- melting_point (float)
- boiling_point (float)
