Question

fluorine has 7 valence electrons. which charge is its ion likely to have? (1 point)
○ 1–
○ 5+
○ 5–
○ 1+

Explanation:

Fluorine is a non - metal. Atoms tend to achieve a stable electron configuration (usually an octet, 8 valence electrons) by gaining or losing electrons. Fluorine has 7 valence electrons. To reach the stable octet configuration, it is easier for fluorine to gain 1 electron. When an atom gains an electron, it acquires a negative charge. The magnitude of the charge is equal to the number of electrons gained. Since fluorine gains 1 electron, its ion will have a charge of \(1^-\).

Answer:

A. \(1^-\)
