Flourine has an atomic number of 9. You would expect fluorine would like to do which of the following?

A.

give up all seven electrons, acquiring a positive charge

B.

to be nonreactive with other atoms

C.

to accept an electron from another atom, acquiring a negative charge

D.

to give up four of its electrons, acquiring a positive charge

Answer and Explanation

The Correct Answer is C

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.
