Step 1

A. Fluorine atoms gain an electron more readily than the other Group 7 elements.

Answer

This option correctly identifies that fluorine's high reactivity is largely due to its ability to gain an electron easily. As the most electronegative element, fluorine has a strong tendency to attract electrons, making it highly reactive.

Step 2

B. Fluorine is a gas.

Answer

While fluorine's gaseous state may have implications for its reactivity, it does not directly explain why it is the most reactive element in Group 7.

Step 3

C. Fluorine exists as diatomic molecules.

Answer

Although fluorine does exist as a diatomic molecule (F2), this fact is not a reason for its reactivity compared to other halogens.

Step 4

D. Fluorine atoms lose electrons more readily than the other Group 7 elements.

Answer

This statement is incorrect; fluorine is known for gaining electrons rather than losing them, which contributes significantly to its reactivity.
