What was discovered
Starting from organometallic compounds, Frankland observes that each element tends to combine with a fixed number of atoms. Valence was the piece that allowed the move from empirical formulae to structures.
What it led to
- Tetravalence of carbon
- Structural theory
- Periodic table (valence as a periodic property)
Built on
- Radical theory and type theory1837-1853
- diethylzinc (Frankland, 1849)
Made possible
- organometallic chemistry
