This is because the metal oxide eats away or corrodes the metallic element. The most common example of this is the rusting of iron (Fe) coines with oxygen gas (O2) in the air to from Iron(III) oxide (Fe2O3) which can be distinguished by its orange-red colour. Iron(III) oxide is also known as rust. The reaction is below: Iron + oxygen Iron(III
