Why do some things float while others sink?

I think the  things that float have more air in it but the ones that can’t float has no air in it so which makes it heavy.   you know what is so weird when you put a peeled orange in water it sinks and when you put in a not peel orange it floats, I think why the thing that floats is because it has air in it but the other thing that is in it has no air in it.
