Explanation

According to the textbook context, an oxygen atom has six valence electrons and requires two more electrons to complete its octet. Similar to how chlorine gains one electron to acquire a negative charge and become a chloride anion (Cl⁻), oxygen will gain two electrons to acquire a negative charge of 2-, forming an anion represented as O²⁻.

Solution Steps

  1. Step 1: Identify that oxygen has 6 valence electrons and needs 2 more to complete its octet.

  2. Step 2: Determine that oxygen will gain 2 electrons to achieve a stable configuration.

  3. Step 3: Conclude that gaining electrons results in a negative charge, forming an anion (O²⁻).
