Solution Steps

Step 1: Identify the oxide ion

An oxide ion is derived from an oxygen atom. Oxygen is in Group 16 of the periodic table and typically gains electrons to achieve a stable electron configuration.

Step 2: Determine the charge

Oxygen atoms have 6 valence electrons and need 2 more electrons to complete their octet. Therefore, an oxygen atom gains 2 electrons to form an oxide ion.

Step 3: Calculate the charge

Gaining 2 electrons results in a charge of \( -2 \) for the oxide ion.

Final Answer

\(\boxed{-2}\)
