A positively charged particle and a negatively charged particle at a distance will attract each other and collide and bounce back and forth forever due to the momentum conservation law.
A positively charged big particle will attract many negatively charged small particles to collide and bounce back and forth around it.
The small negatively charged particles will form into a ball around the big particle and bounce up and down forever.
This is the basic structure of the atoms according to our proven knowledge.
The standard model is all fairy tales, not science, not fact.
