Most of the substances in our body are organic compounds, just like all living things. This includes water. These compounds contain mainly Carbon, Hydrogen, Oxygen, and Nitrogen. All of these, on teh periodic table are classified as "non metals". So the majority of the human body is made of nonmetals.
Cathode rays are electron beams. They're in our televisions.
