Homework Help: AP CHEMISTRY

Posted by Jake on Thursday, January 24, 2008 at 3:59pm.

The unit cells for most alkali metal halides are face-entered for both the cations and anions. In the case of NaCl the sodium ion is just a little too large for the chloride ions to touch each other along the face diagonal. The unit cell edge length is 564.0 pm. The sodium ion has a radius of 95.0 pm. What is the DIAMETER of the chloride ion in picometers?

how would i work out this question?
