Composition of Atomic Particles
I have researched for days and cannot seem to find an answer to several physics/quantum physics questions; but I will ask a single question:
Atoms are said to be made up of energy and particles/subatomic particles. Models show the particles as spherical in shape. What are these (subatomic)particles made of? Are they spheres of energy filled with space?
I have read or heard it referred to as energy or matter, but to my understanding matter is what molecules form. I have heard that the force that holds the particles to orbit the nucleus is energy, but no one seems to say what the particles themselves or composed of.
