Questions: A. Select three of the following modern items or device and conduct an Internet search in order to determine what specific materials are used and what specific properties these material possess in order for the device to function properly 1. Cell phone 2. Solar cells 3. Wind turbine blades 4. Fuel cells 5. Automobile body 6. Kayaks 7. Lightweight bicycle frames 8. Basketballs 9. Digital camera batteries B. We would like to produce a transparent canopy for an aircraft. If we were to use a traditional window glass canopy, rocks or birds might cause it to shatter. Design a material that would minimize damage or at least keep the canopy from breaking into pieces. C. Steel if often coated with a thin layer of zinc if it is to be used outside. What characteristics do you think the zinc provides to this coated or galvanized steel? What precautions should be considered in producing this product? How will the recyclability of the product be affected? D. Write full electronic configurations these atoms: a) Radium b) Silicon c) Bromine d) Thulium for
configurations for these atoms: E. Write core electronic ) Germanium b) Palladium c) Neptunium d) Calcium aba for these ions (hint: more stable, e.g. putting 4p) F. Write full electronic configurations sometimes, half-filled orbitals are 1 e- in each of the p-orbitals in a) Ba 2 b) Sb-3 Co3 Cd1 S2 G. Which 5 elements would have 2 electrons in their outer p-orbitals? H. What does four quantum numbers specify for in Lecture 3? 1. Explain the reason of atomic weights of every element commonly found as not integers? Provide two reasons behind this observation. J. Pauli exclusion principle mentioned that each electron state can hold no more than two electrons and that those electrons must have opposite spins. Thus, provide electron configuration for Fest and S. K. It was found that covalently bonded materials normally found to be less dense as compared to ionically or metallically bonded ones. Describe the reason behind this such observation. L. Describe the bonds responsible for the following by drawing the diagram as well as explanation to strengthen the diagram illustration: a. Brass b. Rubber c. Barium Sulfide d. Solid Xenon e. Bronze f. Nylon g. Aluminum phosphide
