car·bon·i·um

(kar-bon'ē-ŭm),
An organic cation in which the positive charge is on a carbon atom;,for example, (CH3)+. It is now recommended that carbocation be used as the class name and carbenium for specific compound names.

carbocation

An often reactive anion with a positively charged carbon that has six electrons in its outer valence shell—i.e., it is missing two electrons that would ensure maximum stability.
