![]() ![]() So it's clearly the largest of these elements. We want to start with largest first and if we examine the elements, we can see that cesium is furthest to the left and for this town. ![]() So now we want to arrange our moments in decreasing size. And so as we go from right two left, we increase in size and as we go from top to bottom we increase atomic radius. So once again we want to know our trend for increasing size. Ah, the end elements are cesium, antimony, sulfur, lead and selenia. This problem We're asked to arrange some elements in order of decreasing atomic radius. Soon I will work on Problem 64 from chapter eight. So this is the order of decreasing atomic radius for the following elements from largest radius to smallest radius. Therefore it has a smaller atomic radius than SB then SP Excuse me. That s but it's higher than SB and further to the right. It is beneath s so that has a larger atomic radius. So next you have t V right here in the last element is asking us about SC S E s E is located here. Since it's further to the right of CS, the time of Gradus increases from right to left. This is similar to SB, but its further downward and further to the left, that means is going to have a larger atomic radius than SB, but still less than see us. So it's going to go even to the right of the SP that we've chosen before. So that's being close to the top, Right? Means it has a smaller radius. The large atomic radius is over here at the bottom left. So let's look at the rest of the elements We have s as is located here. The radius is going to be smaller than that. So, yes, it's going to be to the left and s. It has a higher time of radio, So the first thing we know that CS is larger than SB. This is going to have a pretty large atomic radius in comparison to SB. It's given us CS five CS and periodic table is located right here. He's a periodic table and we're looking for elements down here to be the largest and the elements over here to have the smallest atomic radio. Which means that elements found right in this area have the largest economic rate is so ask us about C. The trend for time of greatest from the periodic table is this following as we go down, atomic radius increases as we go across this way from right to left the time of great his increases. So we're looking at our periodic table the trend for atomic radius. Chapter three problems 74 says to arrange elements in order of decreasing atomic gradients. ![]()
