The universe is powered by 2 forces, f=m1m2/rr and f=q1q2/rr.
All atoms/masses/bodies connected by m1m2/rr. All charges connected by q1q2/rr.

Atoms are solid balls build by charged particles. Image a positive charged tiny ball/core carries 1000 positive charges, surround by 999 electrons. The electrons will attract to the core and repel each other, form a electron ball around the core, the density of the electron decay at 1/r^3 from the core. Now if there is another particle that carries 1 negative charge but has 100 times volume of an electron, it will attract to the core/electron ball and float on the surface. 

Now if you name the core proton, the electron enertron, the other particle electron, you have a hydrogen atom. Real atom, solid.
