Quick Summary

In chemistry, stability refers to the state of a substance or system continuing without change. This can relate to the ability to withstand force or stress without damage, or a state of constancy.1

In the context of chemical compounds, stability is often achieved when atoms gain or lose electrons to form ions with a full outer electron shell. For example, metals in group IA of the periodic table lose one electron to form stable cations with a +1 charge, while nonmetals in group VIIA gain one electron to form stable anions with a -1 charge. When these oppositely charged ions attract, they form an ionic compound, characterized by a stable ionic lattice structure. Changes in the environment, such as the solvent's polarity, can also influence reaction pathways by affecting the relative stability of initial and transition states.23
