URI: chemrof:valence
Applicable Classes
| Name | Description | Modifies Slot |
|---|---|---|

Properties
- Range: Integer
Aliases
- atom valency
- 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
