Why don't atoms get flattened like Galaxies, solar systems etc., do to conserve angular momentum?

I know that galaxies and solar systems etc., are flat to conserve angular momentum. Why not the same for atoms with electrons rotating around them?

Electrons aren't orbiting the nucleus the same way that planets orbit the sun. Thinking of them as small balls is useful in a classical sense, but not accurate on these small scales. At these scales, it's quantum mechanical. Electrons are not particles circling a nucleus so much as they are probabilistic wave surrounding the nucleus. This is known as the electron cloud. Their shape is determined by their energies.
