Question

fluorine has 7 valence electrons which charge is its ion likely to have
A: 1-
B: 5-
C: 5+
D: 1+

Answer 1

Fluorine has 7 valence electrons and tends to gain 1 electron to achieve a full outer shell, which is characteristic of a stable octet. By gaining 1 electron, fluorine forms an ion with a charge of 1-.

Therefore, the correct answer is:
**A: 1-**
