when we're talking about a subatomic particle defining an element, we should be thinking about the protons and the neutrons. We're excluding the electrons because that was determined the charge. And they're not related to the weight in determining mechanism off, um, element. So you're I have three different opportunities that it could occur where protons are ready are distinct. Just one hydrogen. While the neutron changes, it could be one it could be, too, or it could have none at all. And in all of these cases 12 and three, it is still hydrogen because the prototype is this some type of particle that two trains.
