Dication chemistry
Did you know?
A dication is any cation, of general formula X , formed by the removal of two electrons from a neutral species. Diatomic dications corresponding to stable neutral species (e.g. H 2 formed by removal of two electrons from H2) often decay quickly into two singly charged particles (H ), due to the loss of electrons … See more Some metals are commonly found in the form of dications when in the form of salts, or dissolved in water. Examples include the alkaline earth metals (Be , Mg , Ca , Sr , Ba , Ra ); later 3d transition metals (V , Cr , Mn , Fe , Co , Ni , … See more Multiply-charged atoms are quite common in the Solar system in the so-called Solar wind.
