Chemistry Terms Table of Common Cations

Cations are ions which have a positive electrical charge. A cation has fewer electrons than protons. An ion may consist  of a single atom of an element (a monatomic ion  or monatomic cation or anion) or of several atoms that are bonded together (a polyatomic ion  or polyatomic cation or anion). Because of their net electrical charge, cations are repelled by other cations and are attracted to anions. This is a table listing the name, formula, and charge of common  cations. Alternate names are given for some cations.   Table of Common Cations Cation Name Formula Other Name Aluminum Al3+ Ammonium NH4+ Barium Ba2+ Calcium Ca2+ Chromium(II) Cr2+ Chromous Chromium(III) Cr3+ Chromic Copper(I) Cu+ Cuprous Copper(II) Cu2+ Cupric Iron(II) Fe2+ Ferrous Iron(III) Fe3+ Ferric Hydrogen H+ Hydronium H3O+ Oxonium Lead(II) Pb2+ Lithium Li+ Magnesium Mg2+ Manganese(II) Mn2+ Manganous Manganese(III) Mn3+ Manganic Mercury(I) Hg22+ Mercurous Mercury(II) Hg2+ Mercuric Nitronium NO2+ Potassium K+ Silver Ag+ Sodium Na+ Strontium Sr2+ Tin(II) Sn2+ Stannous Tin(IV) Sn4+ Stannic Zinc Zn2+
