Thank you!
How exactly did you work this out? I managed to get the first 2 right, but I could not work out the basis of the crystal structure.

P.S this question is copied word for word in an Edx online course. I do not mind if someone asked HOW to do it, but asking for the answer is a bit lazy. next time, could you please not go and as such a question in such a way? and also, to any OTHER Edx students reading this, please don't cheat. the answers to the question are in the video if you look hard enough, and think hard enough.
