Question

States of Matter; Liquids and Solids entials: Solution ork solid a. Ammonia has a molecular structure: therefore, it freezes as a molecu b. Cesium is a metal; it is a metallic solid. c. Cesium iodide is an ioni it exists as an ionic solid. d. Silicon atoms might be expected to form bonds to other silicon atoms, as carbon does in diamond. A covalent solid would result. Answer Check Make sure you correctly understand the bonding invol Exercise 11.8 Classify each of the following solids according to S the forces of attraction that exist between the structural units. a. zinc, Zn b. sodium iodide, Nal c. silicon carbide, SiC d. methane, CH4 Physical Properties Many physical properties of a solid can be directly related

Explanation / Answer

a)

Zn --> metallic bonding

b)

NaI --> ionic bonding

c)

Molecular / covalent bonding (solid crystal)

d)

methane, nonoplar covalent bonding (gas)

the order:

NaI > Zn > SiC > CH4
