Which of the following is not use of compounds of Fluorine________________?
Correct answer: D. None of the above
- A. SbF3 is used for manufacture of pottery
- B. Sodium fluoroacetate is a rat poison
- C. Cu F2 is used in ceramic industry
- D. None of the above
Explanation
All three listed fluorine compounds have recognized uses: antimony(III) fluoride is used in pottery-related work, sodium fluoroacetate is a rat poison, and copper(II) fluoride is used in the ceramic industry. Hence none of the first three is an incorrect use. Students may choose SbF3 because its pottery application is less familiar than the poison use of sodium fluoroacetate.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
