Concept explainers
a)
Interpretation: Number of cannonballs, type of packing and type of regular geometry to be found.
Concept introduction
Closest packing: A metallic crystal containing spherical atom that are equally connected to each other in all direction. We can show such a structure by uniform packing in the way the sphere uses the vacant space. Closest packing are two types are Cubic close packing and Hexagonal close packing.
Cubic close packing: The arrangement of abc have cubic close packing. In this packing, unit cell made-up of four layers of atom. The top layer and bottom layer made-up of six atoms at hexagon’s corner and one at hexagon’s center.
Hexagonal close packing: In this packing, unit cell made-up of three layers of atom. The top layer and bottom layer made-up of six atoms at hexagon’s corner and one at hexagon’s center.

Chemistry: An Atoms First Approach
- Using circles, draw regular two-dimensional arrangements that demonstrate low packing efficiency and high packing efficiency.arrow_forwardAn amorphous solid can sometimes be converted to a crystalline solid by a process called annealing. Annealing consists of heating the substance to a temperature just below the melting point of the crystalline form and then cooling it slowly. Explain why this process helps produce a crystalline solid.arrow_forwardWhat feature characterizes the dynamic equilibrium between a liquid and its vapor in a closed container?arrow_forward
- 8.45 Describe how interactions between molecules affect the vapor pressure of a liquid.arrow_forwardSilicon carbide, SiC, is a very hard, high-melting solid. What kind of crystal forces account for these properties?arrow_forward8.103 In previous chapters, we have noted that cryolite is used in refining aluminum. Use the web to look up what this addition does for the process, and relate it to the concepts of intermolecular forces from this chapter.arrow_forward
- Calculate the percent of volume that is actually occupied by spheres in a face-centered cubic lattice of identical spheres. You can do this by first relating the radius of a sphere, r, to the length of an edge of a unit cell, l. (Note that the spheres do not touch along an edge but do touch along the diagonal of a face.) Then calculate the volume of a unit cell in terms of r. The volume occupied by spheres equals the number of spheres per unit cell times the volume of a sphere (4r3/3).arrow_forwardA common prank on college campuses is to switch the salt and sugar on dining hall tables. which is usually easy because the substances look so much alike. Yet, despite the similarity in their appearance, these two substances differ greatly in their properties because one is a molecular solid and the other is an ionic solid. How do the properties differ and why?arrow_forwardThe molar heat of fusion of sodium metal is 2.60 kJ/mol, whereas its heat of vaporization is 97.0 kJ/mol. a. Why is the heat of vaporization so much larger than the heat of fusion? b. What quantity of heat would be needed to melt 1.00 g sodium at its normal melting point? c. What quantity of heat would be needed to vaporize 1.00 g sodium at its normal boiling point? d. What quantity of heat would be evolved if 1.00 g sodium vapor condensed at its normal boiling point?arrow_forward
- Consider the CsCl unit shown in Figure 9.21. How many Cs+ ions are there per unit cell? How many Cl- ions? (Note that each Cl- ion is shared by eight cubes.)arrow_forwardWhy do liquids have a vapor pressure? Do all liquids have vapor pressures? Explain. Do solids exhibit vapor pressure? Explain. How does vapor pressure change with changing temperature? Explain.arrow_forward
