Hello Everyone in this video. We're given these four different illustrations here. We're trying to identify the illustration that depicts a collection of nitrogen try fluoride. Alright, so, we're given from the problem that our blue spheres are going to be nitrogen. So, we have nitrogen here and then our flooring atoms are going to be green or yellowish. I just picked it as green and we have three of those according to our molecule here. So, I have something maybe like this. All right. You can see here then that our ratio is going to be 123. So, yeah. 123. All right. So let's see. We can see right away that for illustration see that we have only purely nitrogen and flooring di atomic molecules. This definitely incorrect. Alright, and again, we're looking for only one central nitrogen or one central blue sphere and then we have three green spheres. This one right here is incorrect ratio. We have kind of the opposite instead of one nitrogen and three florins. We have three nitrogen and one flooring over here. So this is also again incorrect because the ratios are off as for this one right here, we only have three total atoms. We need foreigner molecule. So this is incorrect. And lastly, we just have D. And that is the correct answer. Even if we did not do the process of elimination, we can see that still we have one central nitrogen adam here in the center here and we have three of these greenish spheres of surrounding the central nitrogen. So depiction D. Is going to be my final answer for this problem.
