The thing is that the evidence suggests that what you are looking for does not exist. That is, you're imagining that these particles must be something like tiny little spheres that have real trajectories. The evidence suggests that it's not just that we cannot precisely measure the position and momentum of an electron at the same time. It's that an electron doesn't even have a precise position and momentum at the same time. The quantum uncertainty isn't just because trying to measure something inevitably disturbs it. It's because, at it's smallest level, electrons and photons and everything else do not behave like little classical particles. I don't think you'll be able to understand the "true composition of the atom" until you can let go of your ideas about what that composition has to be like, and be open to the idea that the way the universe really works is much, much stranger than we might imagine from our everyday experience.
