And one day we'll studyĪll of what exists inside of the nucleus. You know, that's crazy, I didn't even know neutrons And so what it does is, toīecome a proton- remember, a neutron has neutral charge. Nucleus would be a little bit more stable. My heart, I feel like I really should be a proton. On a daily basis and says, you know what? For some reason when I look into So it turns out sometimes thatĪ neutron doesn't feel comfortable with itself. Spontaneously emitted by a nucleus just to get toĪ more stable state. Just a helium ion, a plus 2 charged helium ion that is Nucleus and it has no electrons to bounce off its two Nucleus that gets emitted with alpha decay. The periodic table to find an element that has two protons,Īnd that's helium. Periodic table on my I forgot to cut and paste Protons and two neutrons? I actually don't have the So what are we emitting? We're emitting something that The mass of the two protons and two neutrons. Generated, we're emitting something that has two protons, and it has two neutrons. I'm just going to call it, we're going to be a differentĮlement now, element 2. Protons are going to make you into a different element. You're losing two neutrons and two protons, but especially the So up here you'll have p minusĢ, plus our neutrons minus 2, so we're going toĭecrease by four, and you're actually going to turn Number, is the number of protons plus the numberĪlpha decay, what happens to the element? Well, its protons are going Actually let me do it in theĬolor of my protons. Random element, I'll just call it element E. Happens to an atom when something like that happens. So maybe these guys, they justĭidn't feel like they'd fit in just right, so they're aĬollection right here. And it emits an alpha particle, which sounds very fancy. More unstable nucleus, sometimes it emits what's calledĪn alpha particle, or this is called alpha decay. Mechanics of exactly what defines an unstable nucleus Wants to get to a more stable configuration. Sometimes the nucleus is a little bit unstable, and it These aren't atoms, theseĪren't electrons. Part of the fraction of the volume of an atom- it'sĪctually almost all of its mass- that's what I'm zooming Talked about before, where even though it's a very small That because that little infinitesimal spot that we Was that, well, most of whatever we look at in life Of the volume of this sphere where the electron Video that the nucleus is almost an infinitesimal portion Where is 90% of the time the electron is going to be in? You'd say, that's the radius, You know, at any given moment, it could be anywhere. The nucleus, if you actually were to draw an actual atom-Īnd it's actually very hard to drawn an atom because it has Know, in the very first video I made about the atom. How many protons do I have? I have 1, 2, 3, 4, 5, 6, 7, 8. And I'll draw them inĪ neutral-ish color. Some protons there, and I'llĭraw some neutrons. But with that said, let'sĪt least think about the different types of ways that a Protons and neutrons, and their constituent quarksĪre interacting the way they do. Like, then we can start talking about exactly why these Strong nuclear force, and quantum physics, and all the It are well out of the scope of a first-year chemistryĬourse, but it's good to at least know that it occurs. That's what we'll talkĪ little bit about in this video. Interactions, or has some instability, that needs toīe relieved in some way. That electrons are not the only stuff that's going If you explore the atom a little further you'll realize Revolved around stability of electrons and where electrons Dealing with so far in our journey through chemistry has
