Okay, so the unit cells for cesium chloride and barium chloride are shown here.
00:09
Show the ratio of catamins to an an an in each of the unit cells, corresponding to the ratios of catarans to an an an an in the formula of each compound.
00:18
Okay, so let's start with cesium chloride.
00:22
Well, we see that cesium, the purple atom, there is one cesium for every one, two, or one, two, three, four, five, six, seven, eight, chorines, so that's eight corin.
00:35
So our ratio is 1 to 8.
00:38
Now for barium chloride, let me fill in chloride in red because it's sort of hard to see.
00:51
Okay.
00:53
So for barium, we have how many atoms, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.
01:06
So there's 14 bariums, which would be and then the number of chlorides is 1, 2, 3, 4, 5, 6, 7, 8.
01:23
8 corids...
