A substance that can not be decomposed into simpler substance by a chemical or physical means is a chemical element.
This is called an element.

Element
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 :)
The fact that it can no longer be broken down. An element is pure because of how it cannot be broken further down.
cannot be broken down into other substances
An element is a substance that is composed entirely of a single type of atom and cannot be broken down any further by chemical means. Earth is a mixture that does not even have a definite composition. It may include various minerals and organic substances. Air is a mixture of a variety of gasses, primarily nitrogen and oxygen. Water is a chemical compound of the elements hydrogen and oxygen. Fire is not event a substance in its own right but a chemical process; it is a chemical reaction between oxygen and some flammable material.
Carbon is an element. It cannot be broken down further into simpler substances through chemical means, and contains only one type of atom - carbon atoms. C is the chemical symbol for carbon.
An element is a pure substance that cannot be broken down into simpler substances by chemical means.
The atom cannot be broken by chemical methods.
No. Elements cannot be broken down into simpler substances in a chemical reaction.
All of the elements of the Periodic Table cannot be broken down into simpler substances.

an element is a substance that cannot be broken down into a simpler form by chemical means
A pure substance that cannot be broken down into simpler substances by physical or chemical means is an element. This is because Elements can't be broken down chemically into other substances because there is nothing to break them down into.

These are the chemical elements.
