Correct Answer is C
Explanation
A. give up all seven electrons, acquiring a positive charge: Fluorine has 7 valence electrons and needs 1 more to complete its outer shell; it’s unlikely to give up 7.
B. to be nonreactive with other atoms: Nonreactive atoms have full outer shells, like noble gases. Fluorine is highly reactive.
C. to accept an electron from another atom, acquiring a negative charge: Fluorine is highly electronegative, so it gains 1 electron, becoming a negative ion (anion).
D. to give up four of its electrons, acquiring a positive charge: Fluorine doesn’t have four valence electrons to give; it wants one more, not to lose.
