Explanation:

Step1: Recall oxygen's position

Oxygen is in Group 16 and Period 2. So the first two options are incorrect.

Step2: Determine its type

Oxygen is a non - metal, so the third option is correct.

Step3: Analyze electron behavior

Oxygen gains two electrons to form a stable ion with a - 2 charge, not lose two electrons. So the fourth option is incorrect.
