DrRuth says: In all cases, select the answer that BEST answers the question asked. All questions on this sample exam are worth the same number of points. On the real exam, the harder/longer questions will be worth more points. Read the whole thing first and plan which to answer first because you feel confi- dent about them. Notice the hardest ones and save them till last so you don’t use up all your time working on them. Shear 52375 The table below lists electronegativity val- ues for the first six rows. The bottom row and the lanthanides and actinides list atomic weights.
