WebThe Uses of Ions in Living Organisms Ions are atoms or molecules with a charge- they get this charge by gaining electrons to form negative ions called anions and losing electrons to form positive ions called cations. Atoms and molecules become charged because it makes them more stable, and this state takes less energy to maintain. WebSep 22, 2024 · Oxidation is the loss of electrons and reduction is the gain of electrons. We know these basic definitions. The formation of ionic compounds can be explained on the basis of these definitions. However, these definitions of oxidation and reduction are unable to explain the formation of molecular compounds.
