, 2 THE NATURE OF MATERIALS YH YH YH




Review Questions
YH



2.1 The elements listed in the Periodic Table can be divided into three categories. What
YH YH YH YH YH YH YH YH YH YH YH YH Y H Y


are these categories and give an example of each?
H YH YH YH YH YH YH YH YH




Answer. The three types of elements are metals (e.g., aluminum), nonmetals (e.g., oxygen), an
YH YH YH YH YH YH YH YH YH YH YH YH YH


d semimetals (e.g., silicon).
YH YH YH



2.2 Which elements are the noble metals?
YH YH YH YH YH




Answer. The noble metals are copper, silver, and gold.
YH YH YH YH YH YH YH YH



2.3 What is the difference between primary and secondary bonding in the structure of materials?
YH YH YH YH YH YH YH YH YH YH YH YH YH




Answer. Primary bonding is strong bonding between atoms in a material, for example to fo
YH YH YH YH YH YH YH YH YH YH YH YH YH YH


rm a molecule; while secondary bonding is not as strong and is associated with attraction
YH YH YH YH YH YH YH YH YH YH YH YH YH YH Y


Hbetween molecules in the material.
YH YH YH YH



2.4 Describe how ionic bonding works?
YH YH YH YH




Answer. In ionic bonding, atoms of one element give up their outer electron(s) to the atom
YH YH YH YH YH YH YH YH YH YH YH YH YH YH YH


s of another element to form complete outer shells.
YH YH YH YH YH YH YH YH



2.5 What is the difference between crystalline and noncrystalline structures in materials?
YH YH YH YH YH YH YH YH YH YH




Answer. The atoms in a crystalline structure are located at regular and repeating lattice po
YH YH YH YH YH YH YH YH YH YH YH YH YH YH


sitions in three dimensions; thus, the crystal structure possesses a long-
YH YH YH YH YH YH YH YH YH YH


range order which allows a high packing density. The atoms in a noncrystalline structure a
YH YH YH YH YH YH YH Y H YH YH YH YH YH YH


re randomly positioned in the material, not possessing any repeating, regular pattern.
YH YH YH YH YH YH YH YH YH YH YH



2.6 What are some common point defects in a crystal lattice structure?
YH YH YH YH YH YH YH YH YH YH




Answer. Some of the common point defects are: (1) vacancy -
YH YH YH YH YH YH YH YH YH YH


a missing atom in the lattice structure; (2) ion-pair vacancy (Schottky defect) -
YH YH YH YH YH YH YH YH YH YH YH YH YH


a missing pair of ions of opposite charge in a compound; (3) interstitialcy -
YH YH YH YH YH YH YH YH YH YH YH YH YH YH


a distortion in the lattice caused by an extra atom present; and (4) Frenkel defect -
YH YH YH YH YH YH YH YH YH YH YH YH YH YH YH YH


an ion is removed from a regular position in the lattice and inserted into an interstitial p
YH YH YH YH YH YH YH YH YH YH YH YH YH YH YH YH YH


osition not normally occupied by such an ion.
YH YH YH YH YH YH YH



2.7 Define the difference between elastic and plastic deformation in terms of the effect on t
YH YH YH YH YH YH YH YH YH YH YH YH YH YH


he crystal lattice structure.
YH YH YH




Answer. Elastic deformation involves a temporary distortion of the lattice structure that is
YH YH YH YH YH YH YH YH YH YH YH YH YH


proportional to the applied stress. Plastic deformation involves a stress of sufficient magni
YH YH YH YH Y H YH YH YH YH YH YH YH


tude to cause a permanent shift in the relative positions of adjacent atoms in the lattice. P
YH YH YH YH YH YH YH YH YH YH YH YH YH YH YH Y H


lastic deformation generally involves the mechanism of slip -
YH YH YH YH YH YH YH YH


relative movement of atoms on opposite sides of a plane in the lattice.
YH YH YH YH YH YH YH YH YH YH YH YH YH



2.8 How do grain boundaries contribute to the strain hardening phenomenon in metals?
YH YH YH YH YH YH YH YH YH YH YH




Answer. Grain boundaries block the continued movement of dislocations in the metal duri
YH YH YH YH YH YH YH YH YH YH YH YH


ng straining. As more dislocations become blocked, the metal becomes more difficult to def
YH Y H YH YH YH YH YH YH YH YH YH YH YH


orm; in effect it becomes stronger.
YH YH YH YH YH



2.9 Identify some materials that have a crystalline structure.
YH YH YH YH YH YH YH
