these are the answers to the chapter 7 & 8 practice quiz we begin with multiple-choice questions number 1 this question is asking you to predict the values for atomic radius and first ionization energy for potassium so based on periodic trends we know that potassium should be having a larger atomic radius than calcium so therefore the correct answer is either C or D because 196 is larger than 174 and since potassium has a larger atomic radius it should have a smaller value for first ionization energy in other words it should require less energy to remove an electron from potassium than it does from calcium so therefore looking for a smaller first ionization energy than 590 correct answer is C in number 2 we're still talking about periodic trends which the following properties tend to decrease as you go from top to bottom down a group in this case group 14 well as you can see atomic radius generally tend to increase from top to bottom down a group so the correct answer is not a with res
