Which of the elements in the table below would react more readily with chlorine?
Element | Ionization energy (KJ \(mol^{-1} \times 10^{-3}\)) |
| W | 12.0 |
| X | 21.0 |
| Y | 106.0 |
| Z | 200.0 |
- A. Y and Z only
- B. X and Z only
- C. W and X only
- D. W and Z only
Correct Answer: C. W and X only
Explanation
Among the given elements, W has the lowest ionization energy (\(12.0 KJ mol^{-1} x 10^{-3})\), indicating that it would be more likely to react with chlorine. X has a higher ionization energy \((21.0 KJ mol^{-1} x 10^{-3})\), so it would be less reactive with chlorine compared to W.
Based on ionization energy values, the elements that would react more readily with chlorine are W and X.
