Why Do Atoms Form Chemical Bonds? Atoms form chemical bonds because a bonded system can achieve a more stable electronic arrangement. The electrons involved in bonding are mainly the valence electrons . For many main-group elements, stability is associated with achieving a noble-gas-like valence-shell configuration. This is commonly described using the octet rule , although the octet rule has important exceptions. Core idea: Chemical bonding is fundamentally an interaction involving electrons and nuclei. The arrangement of these interac...
