Key Concepts

Electron Configuration

This concept refers to the arrangement of electrons in atomic orbitals around the nucleus. For representative elements, electrons are distributed in s and p orbitals, which play a fundamental role in chemical reactivity and ion formation.

Order of Electron Removal

In ion formation for representative elements, electrons are typically removed starting from the highest energy orbitals. This means that even if an s orbital is filled earlier than a p orbital, the electrons in the s orbital can be lost first when forming positive ions, as they are often higher in energy in the ionized state.

Noble Gas Configuration and Stability

The stability of ions is largely related to achieving a noble gas configuration, which denotes a filled valence shell (usually an octet for p-block elements). Many ions formed from representative elements lose electrons to reach a configuration that mirrors that of the nearest noble gas, thus minimizing energy and increasing stability.
