Question

fluorine, which has 7 valence electrons, is going to...
give up 7 electrons
gain 1 electron

Explanation:

Fluorine has 7 valence electrons. To achieve a stable octet (8 valence electrons), it is easier for fluorine to gain 1 electron rather than give up 7 (which would require a large amount of energy). So the correct choice is "Gain 1 electron".

Answer:

Gain 1 electron
