The chloride ions in a sodium chloride crystal are in a face-centered cubic lattice. Even though they touch sodium ions, the chloride ions do not touch each other. A sodium ion has a radius of 99 pm, and a chloride ion has a radius of 181 pm. How far apart are the chloride ions at their closest point? Please explain how and why you find the hypotenuse, edges, and gaps and why you use certain values. Thank you.
