, 2 THE NATURE OF MATERIALS RS RS RS




Review Questions
RS



2.1 The elements listed in the Periodic Table can be divided into three categories. What ar
RS RS RS RS RS RS RS RS RS RS RS RS R S RS


e these categories and give an example of each?
RS RS RS RS RS RS RS RS




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


semimetals (e.g., silicon). RS RS



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




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



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




Answer. Primary bonding is strong bonding between atoms in a material, for example to form
RS RS RS RS RS RS RS RS RS RS RS RS RS RS


a molecule; while secondary bonding is not as strong and is associated with attraction betw
RS RS RS RS RS RS RS RS RS RS RS RS RS RS RS


een molecules in the material.
RS RS RS RS



2.4 Describe how ionic bonding works? RS RS RS RS




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


of another element to form complete outer shells.
RS RS RS RS RS RS RS



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




Answer. The atoms in a crystalline structure are located at regular and repeating lattice posit
RS RS RS RS RS RS RS RS RS RS RS RS RS RS


ions in three dimensions; thus, the crystal structure possesses a long-
RS RS RS RS RS RS RS RS RS RS


range order which allows a high packing density. The atoms in a noncrystalline structure are
RS RS RS RS RS RS RS R S RS RS RS RS RS RS RS


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



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




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


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


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


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


RSan ion is removed from a regular position in the lattice and inserted into an interstitial posi
RS RS RS RS RS RS RS RS RS RS RS RS RS RS RS RS


tion not normally occupied by such an ion.
RS RS RS RS RS RS RS



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


crystal lattice structure.RS RS




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


oportional to the applied stress. Plastic deformation involves a stress of sufficient magnitude
RS RS RS RS R S RS RS RS RS RS RS RS


to cause a permanent shift in the relative positions of adjacent atoms in the lattice. Plastic d
RS RS RS RS RS RS RS RS RS RS RS RS RS RS RS R S RS


eformation generally involves the mechanism of slip -
RS RS RS RS RS RS RS


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



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




Answer. Grain boundaries block the continued movement of dislocations in the metal during
RS RS RS RS RS RS RS RS RS RS RS RS R


straining. As more dislocations become blocked, the metal becomes more difficult to deform; i
S R S RS RS RS RS RS RS RS RS RS RS RS RS


n effect it becomes stronger.
RS RS RS RS



2.9 Identify some materials that have a crystalline structure.
