Question

Problem Solving Practice: Problem solving usually involves multiple steps (e.g. analyzing, planning solving and assessing). For the questions below, we will try the following strategy: Predict/Justify. Predict: For each of the following pairs, circle the atom or ion having the larger radius. S or 0 Na^+ or K^+ Justify: Why did you choose the answers above? Did all the group member choose the same atom or ion? Now justify your choice and discuss it within your group. Predict: Will sulfur have a higher or lower ionization energy than phosphorus? _____ Justify: Rationalize your choice and discuss it within the group. Predict: A student proposes to measure the electron affinities of argon and nitrogen. Do expect him to succeed? Justify: Defend your answer and discuss it among the group.
