Hello,
Well,You have to understand pretty much everything,So look,If you know the number of protons or electron then you will know its atomic number,and if you know the number of protons and neutrons then you will know the mass of the element.So yeah,this is basically all you need to know to understand the unified structure of atom to help you better understand an element that was unfamiliar to you!
