Predict the coordination numbers (CN) of Ca2+ in CaCl2 and CaBr2 using the following information: Ionic radius of Ca2+ = 114 pm in CN = 6; and 126 pm in CN = 8 Ionic radius of Cl- = 167 pm in CN = 6 Ionic radius of Br- = 182 pm in CN = 6

Step 1
The coordination number of an ion in a crystal is the number of immediate neighbor ions surrounding it. This number is largely determined by the ratio of the ionic radii of the cation and anion involved. Show more…

For sodium chloride, Na+ and Cl- each has ionic radius of 102 pm and 181 pm respectively. Calculate the radius ratio and use this information to predict the close packing structural arrangement of the anions and cations, and the coordination number of each ion.

The coordination number (CN) is the number of adjacent ions (or atoms) surrounding the reference ion (or atom). Given rO2- = 0.132 nm and rSi4+ = 0.039 nm, estimate the CN for the cation of SiO2.

For a coordination number of four, the radius of $\mathrm{Mn}^{7+}$ has been estimated to be $39 \mathrm{pm}$. Estimate the charge density for the $\mathrm{Mn}^{7+}$ ion. Express your answer in $\mathrm{Cmm}^{-3} .$ How does this compare with the charge density of $\mathrm{Be}^{2+}$ given in Table $21.4 ?$ Would you expect the bonding in $\mathrm{Mn}_{2} \mathrm{O}_{7}$ to be primarily ionic or primarily covalent? Explain.
