f

f

+1+2+3-1-2-3

Explanation:

• Metal or non - metal: Fluorine (\(F\)) is in Group 17 (halogens) of the periodic table. Halogens are non - metals. They have high electronegativity and tend to gain electrons rather than lose them.
• Cation or anion: Fluorine has 7 valence electrons. To achieve a stable octet (8 - electron configuration), it gains 1 electron. When an atom gains electrons, it forms a negatively charged ion. A negatively charged ion is called an anion. The ion formed by fluorine is \(F^-\).

Answer:

• Is this element a metal or nonmetal? Nonmetal
• Is the formed ion a cation or an anion? Anion
