Iron | Introduction to Chemistry

Iron reacts with oxygen in the air to form various oxide and hydroxide compounds; the most common are iron(II,III) oxide (Fe 3 O 4) and iron (III) oxide (Fe 2 O 3). Iron(II) oxide also exists, although it is unstable at room temperature. These oxides are the principal ores for the production of iron.
