MEEN 222-503 HOMEWORK #1 1. What are the key components of materials science and engineering? What are their relations? 2. Callister 2.5 (7 th and 8 th ed.) 3. Callister 2.18 (7 th and 8 th ed.) 4. What are the electron configurations for C, Na, Cl, Si, Ar, Na + , Cl - ? 5. Why does the thermal expansion coefficient vary reversely correlated with melting temperature? 6. Why does a higher melting point correspond to a larger Young’s modulus (E)? 7. Describe briefly the 3 types of strong bonds that can form between atoms in a solid.

Unformatted text preview: What do melting temperatures tell us about bond strength? 8. A copper penny has a mass of 2.60 grams. (a) Give the electronic configuration of copper and indicate which electrons participate in bonding, (b) Calculate the number of copper atoms in the penny (assume that the penny is composed entirely of pure copper). (c) Calculate the number of copper atoms in mole unit (or how many moles of Cu atoms in a penny?)...
