Solution

Solution Steps

Step 1: Determine the Normal Electron Count for Oxygen

Oxygen normally has 8 electrons because its atomic number is 8.

Step 2: Identify the Charge with 9 Electrons

If oxygen has 9 electrons, it has gained an extra electron compared to its neutral state. This means it has a negative charge.

Step 3: Determine the Type of Ion

An ion with a negative charge is called an anion.

Final Answer

The answer is B (Negatively charged anion).

$\boxed{\text{B}}$
