ELI5: Whats in between an atom?

So my (basic) understanding of atoms is you have a nucleus (also always wondered what exactly a nucleus is made of) and then you have the electrons orbiting around it, like a ring around Saturn. My question is, what is between the ring and the nucleus?

Nothing, just empty space.  
Also, to be more specific, it's not really a ring, more like a cloud (called the atomic orbital) that can have different forms. It describes the position of the electron (as a wave) or a chance of it being located at any specific point (as a particle), quantum mechanics are complicated.
