Question

Please explain how to write unabbreviated and abbreviated electron configurations with ions?

Answer 1

Unabbreviated: starts from the very beginning of the periodic table and continues all the way to the element.

Example: for aluminum: 1s2 2s2 2p6 3s2 3p1

Abbreviated: starts from the last noble gas electronic configuration before reaching the element.

Example: for aluminum: [Ne] 3s2 3p2
