Chapter 03: Physical and Mechanical Properties of Dental Materials MULTIPLE CHOICE 1. Which type of bond occurs when two atoms share electrons in their outer shell, creating full shells for both? a. Ionic bond b. Covalent bond c. Metallic bond d. Hydrogen bond ANS: B Covalent bonds occur when two atoms share electrons in their outer shell, creating full shells for both. Covalent bonds are very strong. Diamond is a good example of a strong covalent bond; it is hard and has a high...

What kind of test is depicted by a stress-strain diagram? - answer-tensile test What term is used for the ratio of stress to strain below the proportional limit? - answer-Young's modulus What does the impact test measure? - answer-toughness What is true regarding the ductile-to-brittle transition temperature? - answer-It is important for structures used in cold environments; It is the temperature at which 20 J of energy causes failure in a Charpy V-notch specimen of standard dimensions...
