So why do so many life-forms breathe oxygen? There are probably thousands of kinds of metabolisms, or chemical processes that ...

The number of protons is what defines the element. Oxygen, for example, has eight protons. However, the number of neutrons in ...

As stars evolve, they create heavier elements like oxygen, which get dispersed through their host galaxy after they die. Researchers had thought that, at 300 million years old, the universe was ...
