Thank you for all the answers and sorry for the late reply. I've read through most of what you people have linked and said on the thread and i cannot be more thankful. Thank you once again for explaining.

Hi! I've been wondering about this since i'm a bit confused when it comes to fuel cells. As you can see protons (H+) can go through Electrolyte, but i'm very confused why electrons don't. According to Google, this is how fuel cells work: But in general terms, hydrogen atoms enter a fuel cell at the anode where a chemical reaction strips them of their electrons. The hydrogen atoms are now "ionized," and carry a positive electrical charge. The negatively charged electrons provide the current through wires to do work. This states that the hydrogen atoms becomes ionized (including electrons?) but aren't electrolytes "a liquid or gel which contains ions"? Though i'm not really sure if there are negative/positive ions in electrolyte. This would mean that electrons would also be able to go through (as because they are ions). Here's another statement at (http://chemistry.stackexchange.com/questions/2644/why-dont-the-electrons-move-through-the-electrolyte-instead-of-the-circuit-in) that " Electrons cannot survive in aqueous state". This would completely take off my conclusion of that electrons should be able to go through electrolyte (because they are ions). ------------------------ More statements incoming -------------------------------- As the picture above suggests there are H+ in the electrolyte which i would suppose are protons (positively charge). Does that mean that the electrolyte is positively ionized? ------------------------------ This may be alot of questions at once but i hope you can answer them. Here's a couple of questions i still have in mind - When a hydrogen atom gets separated. The hydrogen atom gets ionized. Does that mean both the proton AND the electron becomes ionized? - How is an electron/proton ionized if the definition of an ion is "an atom or molecule with a net electric charge due to the loss or gain of one or more electrons."? It states that an ATOM that has less/more electrons than protons are ions.

Thanks for the info, i'll be reading all this and i'll come back and see if i've understood it correctly.

Hi forums! Just wanted to start out with a greeting as i'm new to this forum. I'm 14 and i'm in the 9th grade (Swedish school) and we're starting to learn about half-life and radioactivity. I'd really want to know more about it and if anyone knows a way to briefly explain how these two are related to each other and how they work. We haven't gone into it that much and this is why i'm here. Physics and math are my absolute favorite subjects and i want to explore whatever i find within these two subjects deeper and more complicated. This might be much about me but this is to give you an idea of what kind of person i am and how you would be able to explain it to me. All the knowledge we've received are that half-time is the time it takes for an atom to split in half which relates to radioactivity because radioactive decay is when an unstable atom loses energy by discharging ionizing radiation. I interpret it as both are the same thing, i'm not sure if that's correct or not. I am here looking for help. If there are anything you could advice me when it comes to going deeper in physics (from the state where i am now) feel free to tell me, i don't care if its in school or not. Whatever knowledge there are about physics, i'll learn them all. I hope this is not too basic for a forum like this, i really don't know where else to go since talking to the teachers isn't really a good place to look for answers that has nothing to do with school material. (They just don't have the time i guess).
