Nitrogen Clara Maccarald

Take a deep breath, you're breathing in nitrogen! This element makes up 78 percent of the air around us. While nitrogen by itself is incredibly stable, nitrogen compounds have a tendency to explode. Dynamite contains nitrogen, and so do air bags, which use a small explosion to fill up and keep us safe in a car crash. In this informative book, we'll explore this important element, seeing how nitrogen cycles through the environment and even makes up part of our own bodies. Without nitrogen, we wouldn't exist.
