Cesium Chloride Crystal Structure

[chemnerd]

I am working this problem...

I got the answer to a as 0, but don't understand b.

The quick way around part a is just argue that by symmetry all the forces sum to zero, since the attractions cancel pairwise. For part b, do exactly what they say and pull out one of the corner atoms. Some of the symmetries remain(3 pairs) but the remaining attraction is not canceled anymore... Plug and chug the rest into coulomb law. gl!

I can provide some clarification on the topic of cesium chloride crystal structure. The cesium chloride crystal structure is a type of crystal lattice structure that is commonly found in ionic compounds. It is formed when cesium and chlorine ions come together in a 1:1 ratio to create a three-dimensional lattice structure.

In regards to the problem you are working on, it appears that you have correctly identified the lattice constant, or the distance between lattice points, as 0. This is an important parameter in describing the structure of a crystal lattice.

As for part b, it is likely referring to the coordination number of the cesium ions in the crystal structure. Coordination number is a measure of the number of ions or atoms that surround a particular ion or atom in a crystal lattice. In the case of cesium chloride, the cesium ions are surrounded by eight chlorine ions, giving it a coordination number of 8.

I hope this helps to clarify the concept of cesium chloride crystal structure and the problem you are working on. If you have any further questions, please don't hesitate to ask. I am always happy to help others understand scientific concepts.
