The correct name for the ion Fe2+ is

forsale [732]

Fe is the symbol of the metal iron. This is because the Latin name of iron is Ferrum. Iron shows more than one valency and forms Fe2+ and Fe3+ ions. Fe2+ ion is formed when an atom of iron loses 2 electrons to form a cation and Fe3+ ion is formed when an atom of iron loses 3 electrons to form a cation. For this reason, Fe2+ is known as the ferrous ion.

Therefore, the correct name for the ion Fe2+ is ferrous ion.
