How many valence electrons does oxygen have?
Oxygen has six valence electrons.
How to increase blood oxygen level?
If your level is low or you have symptoms (e.g., shortness of breath, bluish lips), seek urgent medical care; improving ventilation, sitting upright, slow deep breathing, and treating underlying causes can help, while supplemental oxygen should only be used under medical supervision.
