Question
Which of the following is a characteristic property of the halogens?A.They are metals.B.They are very stable.C.They are very reactive.D.They are all gases.
Solution
The correct answer is C. Halogens are very reactive. This is a characteristic property of the halogens. They are not metals (option A), they are not very stable (option B), and they are not all gases (option D). Some halogens are gases at room temperature (like Fluorine and Chlorine), but others are liquids (like Bromine), or solids (like Iodine and Astatine).
