What is the difference between hydrogen and oxygen?

Oxygen is a highly electrochemical chemical that is used to rust metals such as iron and aluminum with its acidic forming properties. Oxygen is also vital to our bodies due to its acidifying properties. Sugar and fatty acids in our body become too much, and oxygen breaks down some of them. There is iron in our blood, which rusts with oxygen.

Hydrogen is the first and lightest chemical element that is used for combustion as fuel, for example, when we light a kitchen stove and part of the fire is blue. This blue fire is hydrogen. You can know hydrogen from drinking water because it is made up of two hydrogens.
