Oxygen is the element that gives us life. It is essential for respiration, which is the process our cells use to produce energy. Without oxygen, our bodies wouldn't be able to function properly.
The percentage of oxygen in the atmosphere is 20.75%. The atmosphere has many other elements that we breathe in besides oxygen. Oxygen needs to be present for life on earth.
Oxygen itself is odorless, tasteless, and colorless, so it does not have a specific feeling. However, inhaling fresh oxygen can make us feel refreshed, invigorated, and energized, as it is vital for our body's functioning.
Oxygen is not noxious, as it is essential for human survival. However, inhaling pure oxygen at high concentrations can be harmful and lead to oxygen toxicity.
