Explain why are carbon and copper classified as elements?
An element is a substance that cannot be broken down any further by chemical reactions. While carbon and copper readily combine with other elements to form compounds, they cannot themselves be broken down any further by a chemical reaction. The definition of element (for chemistry) is thus: one of a class of substances that cannot be separated into simpler substances by chemical means What this means is if you take a substance, say .... sugar. You can put it through chemical processes that will reduce it down to its core components. For carbon from sugar, its simple: burn it. The hydrogen and oxygen will burn off as water vapor. Of course, even elements can be broken down, but not by chemical means. The use of a particle accelerator or nuclear fission is required, but I think we can all agree, that is by no means a "chemical" process. That's nuclear :)
