What is Iron oxide (Fe₂O₃)?

Iron oxide is a kind of rock that makes things look red or brown, like the color of dirt after rain.

Imagine you have a bag of red candies, and they’re all stuck together. That’s kind of what iron oxide looks like, tiny pieces of iron mixed with oxygen, holding hands to form something solid. You might find it in rocks, on the ground, or even in some kinds of paint.

Iron oxide happens when iron meets air and gets a little wet, kind of like how your skin turns pink after being outside too long. Over time, this iron and oxygen team up to make something new: red, brown, or even orange stuff that we call rust.

You might see it on the hood of a car that’s been sitting in the rain for a while, that’s rust! Or maybe in your playground when you dig into the ground. Iron oxide is like a big, friendly group party where iron and oxygen hang out together, making cool colors everywhere.
