Electricity so Far

Electricity is a form energy resulting from a current. So I learned that electricity can work in different ways by putting in work and normally electricity which comes from the sun it goes to a electric grid and before it gets to the distribution center it has a substation and powerline and then it goes to a transformer and before the transformer it has a substation and a powerline and the the electricity goes to the people's home. Electricity is a charge produce electromagnetic fields which act on the other charges. I'm still confused about how electricity travels through objects or atoms. I'm getting better at how electricity process in to turning in atom which putting in work with your hands. I have a question about, what's is the name of the wed that has nucleus, blue prontons , red neutron and electrons?
