Question

What is the system name for Fe³⁺ symbol ion?

Answer 1

The
`Fe³⁺ ion` is named iron(III) ion using the Stock system, which uses Roman numerals to indicate the charge of ions for elements with multiple possible positive charges.

Step-by-step explanation:

The system name for the
`Fe³⁺` symbol ion, according to the Stock system of nomenclature, is iron(III) ion. This naming system is used specifically for elements that can form more than one common positive ion. In case of iron, which can have multiple oxidation states the charge on the ion is indicated by a Roman numeral in parentheses following the element's name.

For example the iron(II) ion denotes an
`Fe²⁺ ion`, while the iron(III) ion represents an
`Fe³⁺ ion`. Applying this naming system to compounds, for instance, FeCl₃ should be named iron(III) chloride indicating that the iron ion has a
`3+ charge`, corresponding to the three chloride ions each with a
`1- charge` in the formula.
