ELECTRONIC STRUCTURES OF IONS

This page explores how you write electronic structures for simple monatomic ions (ions containing only one atom) using s, p, and d notation. It assumes that you already understand how to write electronic structures for atoms. 

Working out the electronic structures of ions

Ions are atoms (or groups of atoms) which carry an electric charge because they have either gained or lost one or more electrons. If an atom gains electrons it acquires a negative charge. If it loses electrons, it becomes positively charged.

The electronic structure of s- and p-block ions

Write the electronic structure for the neutral atom, and then add (for a negative ion) or subtract electrons (for a positive ion).
