Practice: What is the full electron configuration of the selenide ion?
The Electron Configuration of Ions involves either adding or removing electrons from a given orbital of an element.
Concept #1: Electron Configurations (Cations)
For Cations, remove electrons from highest shell number (n).
Example #1: Write the condensed electron configuration for the titanium (III) ion.
Concept #2: Electron Configurations (Anions)
For Anions, add electrons to orbital with available space.
Example #2: Write the full electron configuration for the nitride ion.
Practice: What is the full electron configuration of the selenide ion?
Practice: Determine the electron configuration for the Cl+ ion.
Practice: Determine the electron configuration and electron orbital diagram for the silver ion.
