  • valency

Comments

  • forumla: number of electrons in valence shell of free atom – number of non-bonding electrons on atom in molecule
  • forumla: number of bonds + formal charge
  • example: In methane, carbon has a valence of 4, and each hydrogen has a valency of 1
  • example: In in ammonia, nitrogen has a valence of 3, each each hydrogen has a valency of 1
  • todo: determine if this is in CHEBI and how to map
