Question

multiple answer 1 point
which of the following form anions? check all that apply.
sodium
sulfur
magnesium
fluorine

Explanation:

Step1: Recall the definition of anions

Anions are negatively - charged ions. Non - metals tend to gain electrons to form anions.

Step2: Analyze each element

• Fluorine: Fluorine (\(F\)) is a non - metal. It gains one electron to form \(F^{-}\) (an anion).
• Magnesium: Magnesium (\(Mg\)) is a metal. It loses two electrons to form \(Mg^{2 +}\) (a cation).
• Sulfur: Sulfur (\(S\)) is a non - metal. It gains two electrons to form \(S^{2-}\) (an anion).
• Sodium: Sodium (\(Na\)) is a metal. It loses one electron to form \(Na^{+}\) (a cation).

Answer:

Fluorine, Sulfur
