Answer 1

Fluorine, having 7 valence electrons, is likely to gain 1 electron to achieve a full outer shell, which corresponds to the stable electron configuration of the nearest noble gas (neon). When it gains 1 electron, it acquires a negative charge. Therefore, the charge of the fluoride ion (F-) is likely to be:
