Describe the structure of an atom?

So in the middle there are protons and neutrons in the nucleus. Around the nucleus there are electrons which are in shells there are always two electrons in the first shell(closest to the nucleus) and then there are eight in the second shell and in the shell after the second one there are also eight electrons ( depending on the element your looking at). The neutrons have no charge (0) and the protons have a positive charge (+) and the electrons have a negative charge (-). I hope this helps and makes sense. Good luck in your studies
