Random: processing structure properties performance: classification of materials o, bohr atom model, energy/force calculations (lecture 2) 2 xb around, delocalized don"t belong to single atom) nondirectional, nonlocal, can be strong or weak approx. strength: 0. 7-8 ev/atom ex: al electrically conductive, thermally conductive: secondary bonds (relatively weak, van der waals bond ex: h2o. Always present, but to different extents . can be overpowered by stronger primary bonds. More electrons stronger induced dipoles; boiling t increases as you move down the table in noble gas column the more polarizable, the stronger the bonds (how easily it deforms its cloud) Miller indices/planes: how to find miller indices, 1) find intercepts. If any intercept touches the origin, need to shift origin (always show where your origin is) If doesn"t cross a certain axis, can put infinity for that one: 2) take their reciprocals, 3) express that those reciprocals as (#x #y #z) If the # is negative, put bar on top of it.

9. Finally, you should write a program MontrealMaps which will suggest a path to go along the metro to get from one place to another. The only required method for MontrealMaps is a main method but of course you are allowed to write others. Your program should do the following. For any library methods that you use, make sure that you are properly importing things and handling any exceptions they may throw. (10 points) • Using an appropriate library method, you should create a Subway System object. If this method fails to initialize, you should print the message Error, not enough funding. • Use a Scanner and print statements to read the current x and y position of the user. • Use a Scanner and print statements to read the x and y position that the user wants to go to. . Find the nearest Metro Station to both the start position of the user and his final destination. • If the 2 metro stations have the same name (i.e. are the same metro station) then print It is fastest to walk there. • Otherwise, call the method findPath from the previous part to find a path from these 2 metro stations. . If the method returns null, then print Sorry, there is no path on the metro, you'll have to walk • Otherwise, print the path using the metro using the method printPath defined in the MapUtilities class in the appendix.
