Which of the following elements has the higher ionization energy?
Think it through first, then pick an option.
- a Ca

- c Cl
- d F
Answer and explanation
Correct answer: d F
F is at the right of period 2, the smallest, so the highest.
Why the other options are wrong
- a Ca: Ca is in period 4, much bigger than F. The answer is F.
- b K: K is at the left of period 4, among the biggest. The answer is F.
- c Cl: Cl is below F in group 17, so lower. The answer is F.
