Periodic table — 118 elements

Every element of the ABC Chemistry interactive periodic table, one row per element, taken from the same data that draws those pages. The pages cite IUPAC/CIAAW atomic weights, NIST ionization energies and CRC Handbook physical data; values for the heaviest synthetic elements are marked “predicted” where the page marks them, and a property the page does not give is left empty.

  • 118 rows × 85 columns — identity, position in the table, atomic structure, ionization energies, radii, physical and thermal properties, reactions, compounds, abundance, cost, discovery, names in four languages, CAS number, safety, uses.
  • Full files: JSON (366 KB), CSV (115 KB), Excel .xlsx (72 KB). The JSON carries the field list and units with the data.

Gods — 92 deities and 131 relationships

Every deity published in the 4AB Gods section, with names in English, Hindi and Sanskrit, other names, category, tradition and primary association, plus the family and relationship graph used on the family pages — each relationship with its confidence and the texts it rests on. Ids are stable, so the two tables join on them.

  • Deities: 92 rows × 31 columns. Relationships: 131 rows × 9 columns.
  • Full files: JSON with both tables and the category list (141 KB), CSV — deities (34 KB) and relationships (16 KB), Excel .xlsx with one sheet each (27 KB).
  • The list grows as more deity pages are published; a request gets the current version.
