Question

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

Explanation:

• Anions are negatively - charged ions. Non - metals tend to gain electrons to form anions.
• Sulfur (\(S\)) is a non - metal. It gains 2 electrons to form \(S^{2 -}\) anion.
• Fluorine (\(F\)) is a non - metal. It gains 1 electron to form \(F^{-}\) anion.
• Sodium (\(Na\)) is a metal. It loses 1 electron to form \(Na^{+}\) cation.
• Magnesium (\(Mg\)) is a metal. It loses 2 electrons to form \(Mg^{2+}\) cation.

Answer:

Sulfur, Fluorine.
