![]() ![]() Atomic Radius, for the most part, will decrease. And it is as we head towards the top right corner of the periodic table. You just need to understand the general trend. You're not expected to memorize these numbers, so don't worry. So when it comes to atomic radius, these are the ones that are most important. So we just leave them out and realize that we have our other transition metals that are below this, our inner transition metals. There a little bit unstable, so we don't have definitive information on terms of their atomic radius. Metals also realized that the last world, the periodic table, those elements because they're so large and so heavy because they've been synthesized in laboratories. Ah, lot of them happen within the pit here with our transition. Now off course, there's gonna be exceptions here and there. We can see that hydrogen is pretty small at 37 PICO meters and we can see that as we head from hydrogen to helium, there's a small decrease. So if we take a look here, we can see that typically we have our atomic radius given to us within PICO meters. This causes greater attraction to the nucleus which compresses the atomic radius a bit. ![]() We're going to say that the shell number stays constant, but the number of electrons within that shell is increasing. ![]() ![]() So remember, as we had up a group, we say that the number of shells is going to decrease, so this causes a decrease in my atomic radius at the same time as removing from left to right of the periodic table. So remember we said the general trend is as we had from left to right and up a group are atomic radius will decrease. Are atomic radius will decrease? So click on to the next video and let's take a look at what this periodic table would look look like in terms of atomic radius. The overall periodic trend is that as we move from left to right, so remember, we're always heading towards the top right corner of the periodic table. This is going to cause some issues with our atomic radius, so there's an increase in a decrease type of phenomenon happening here with the increase of the number of electrons. But as we add more and more shells, there's gonna be more electrons found within each of those shelves. We're adding more electrons, and as a result our Adam gets larger and larger with more and more shelves. And what this does is it causes a slight decrease in our atomic radius. We're gonna say increasing the number of shell electrons in the same shell causes greater attraction with the nucleus. Though we're going to say that the number of electrons with within the same shell also will increase. But we're going to say, moving across the period. And we're gonna say that the number of electron shells also increase. Now we're gonna say, here, going down a group, we're going to say that the number of electrons increases because our shells get larger and larger and they can hold more and more electrons. Neutrons are neutral and the nucleus itself contains our proton and our neutron. Now remember, within the nucleus we have our protons and neutrons are protons are positively charged particles. The distance between the nucleus and the outer shell is our atomic radius. So here, if we take a look, we have our nucleus in the middle. So Atomic radius is the distance between Adams nucleus and its outer electron shell, otherwise known as its valence shell. ![]()
