What is the name for the Fe2 + cation?

Iron ion

Iron (II) ion

Ironide

Ferride ion

The correct answer is the option: Iron (II) ion.

Explanation:

Hello! Let's solve this!

El Hierro (Fe) has two valence numbers. Fe + 2 and Fe + 3.

The + 2 and + 3 indicate that iron lost two or three electrons respectively.

In this case the ion is Fe + 2, this cation is called the Iron (II) ion

We conclude that the correct answer is the option: Iron (II) ion.

Iron (II) ion.

Explanation:

Fe²⁺ is a cation of ion that lost 2 electrons. It can be named as iron (II) ion. Iron is the name of the metal, and (II) means that it is the cation of Fe metal that lost 2 electrons.

While Iron ion may be Fe²⁺ or Fe³⁺.

So, the right choice is: iron (II) ion.
