That's also clarified in the periodic table of the elements. Oxygen, carbon, chlorine, and sulfur are non-metals. These are just some of the non-metal examples we've given you just to better understand what we're talking about here. Let's start with carbon.While coal forms from the decay of plant matter and the subsequent burial and solidification of leftover carbon, the most common way diamonds are formed is through eruptions shooting upward from the mantle in vertical kimberlite pipes.
