Explain why the heavy stable nuclei tend to have many more neutrons than protons.

Of the repulsive effects off the electrostatic force between protons in the nucleus max for very long range, and hence it effects all the protons within the nucleus. The objective nuclear force or strong force, however, acts over a very short range and only acts on its nearest neighbors. Hence, as the number of protons increase, a number of neutrons has to increase even more, and this will add enough attractive forces to maintain stability within the nucleus.

Okay, so most nuclear i that are stable will end up with an even number of protons and an even number of neutrons. So if we have an even number of protons, that means RZ number has to be even if we have an even number of neutrons as well, they will have to be even okay. Um when we look at our elements now, if both of those numbers are odd, it is very likely that the nucleus is unstable. So we'll focus here on the even numbers for the most part. one of the reasons the odd ones are less stable is because the binding energy keeping all these molecules or keeping all these nucleons together inside the nucleus, the binding energy is actually lower for odd values of Z. And A. If the binding energy is lower, that means the nucleus is held together less strongly and it's more unstable. If these are even that binding energy should go up. Um and the strong force will be able to help keep the particles together um a little bit more easily.

Hand stable item becomes more steeple through radioactive to cake in radioactive decay and unstable, Adam spontaneously releases energy, food, atomic particles, which therefore release energy and make the ADAM any more stable state.

When electricity moves. It's really electrons that are being transferred as they go from Adam Toe Adam. And we can see this when we look at conductors and insulators. Conductors have electrons that are in, um, very loosely bound orbital's, but that means is these electrons that are kind of orbiting. So these dark, these dark circles here are the atomic nuclei. So that's the protons. Um, protons and neutrons are in there and then whizzing around on the outside very, very quickly are electrons and electrons are very light, and they're very fast. And in a conductor, some of the outer electrons in the outer shell are moving around very quickly and very loosely held or loosely bound to the nucleus. And that means that they're kind of more free to flow between the two, any given to nuclei so they can pass between each other. And that's really how electricity is traveled through. Ah, wire, for example, copper wire. But that's only in a conductor in an insulator. Um, the electrons are more loosely sorry, more tightly bound, so elections are a better way of transferring um, charge than protons because protons are tightly, much more tightly bound in the nucleus, and they're also about 2000 times bigger, um, than an electron. So it takes much more force to accelerate a proton than it doesn't electron. And so it's just really the electrons that move around that transfer charge.
