Chapter 7, Problem 86AE
The following observations are made about two hypothetical elements A and B: The A-A and B-B bond lengths in the elemental forms of A and B are 2.36 and 1.94 A, respectively. A and B react to form the binary compound AB2, which has a linear structure (that is
LB - A - B = 180°). Based on these statements, predict the separation between the two B nuclei in a molecule of AB2.

A- Atoms are spherical and so when silver atoms pack together to form silver metal, they
cannot fill all the available space. In a sample of silver metal, approximately 26.0% of the
sample is empty space. Given that the density of silver metal is 10.5 g/cm, what is the
radius of a silver atom?
