Which elements have the highest reactivities?

C. F and Cl

The correct answer is C. F and Cl.
Fluorine (F) is the most reactive element in the periodic table, while chlorine (Cl) is also highly reactive, though less so than fluorine. Reactivity in nonmetals generally increases as you move up and to the right in the periodic table, which is why these halogens are very reactive. If you have more questions or need further assistance, feel free to ask!
The correct answer is C. F and Cl.
Explanation: Fluorine (F) is the most reactive element in the periodic table due to its high electronegativity and small atomic radius, which allows it to attract electrons easily. Chlorine (Cl) is also highly reactive, though not as much as fluorine. Both of these elements are halogens, and they tend to react vigorously with metals and other nonmetals to form ionic and covalent compounds.
The correct answer is C. F and Cl.
Fluorine (F) is the most reactive element in the periodic table, while chlorine (Cl) is also highly reactive, although not as much as fluorine. Reactivity in nonmetals generally increases as you move up and to the right in the periodic table, and these two elements are located in Group 17 (the halogens), which are known for their high reactivity.
