Hello. You'll have to excuse my spelling (If I spelled anything wrong), I'm from Sweden and even though I'm told to be good at English, I'm not an expert. I literally just found this forum in my search for some kind of physics forum where I could ask the following question: Are electrons, protons and neutrons build-stones in them-self or is it first when they're combined - making some type of atom they become a build-stone - an atom? I'm not some kind of physics enthusiast and this is not a question I got from home work. It's simply a question I find interesting, so I told my friend to think about and we came up with two different answers - yes, and no.
