Question

Flourine has 7 valence electrons. Which charge is it's ion likely to have

Answer 1

Fluorine has 7 valence electrons and needs to gain 1 additional electron to reach a full octet (8 valence electrons), which is the most stable configuration for it. When it gains this extra electron, it becomes negatively charged. Therefore, the ion formed by fluorine is likely to have a charge of -1, resulting in the fluoride ion (F⁻).
