Atoms are the most smallest particles , they can only be seen by the most powerful microscope
In a atom there are electrons , protons and neutrons
The green marbles in a ball like structure are the neutrons
The protons are with neutrons together bonded by strong force
Proton have positive charge while neutrons have no charge
The rings are a metaphor which describes electron movement and spin , they actually do not exist
The electrons spin around the nucleus
Electrons contain negative charge
Why electron does not get attracted to proton ?
The protons are attracted to neutrons due to the strong force , electrons cant get attracted due to electromotive force that made electrons move rather than getting attracted
