Element Compounds can be broken down to elements (atoms) which cannot be decomposed further into simpler substances (that's why they're called a-toms, from Greek 'à-tomos', meaning 'un-sliceable'.
Well...there's NOTHING that can't be decomposed into simpler subjects if you're willing to work hard enough at it, but without huge machines you can't break atoms of single elements into simpler substances.
An element is a material that cannot be decomposed into simpler substance by ordinary chemical means. This differs from compounds, which can be decomposed into the elements that make them.

Elements cannot be changed into simpler substances by chemical means. To change them into simpler particles, you need nuclear means.
These are the chemical elements.
All of the elements of the Periodic Table cannot be broken down into simpler substances.
because a substance cannot be decomposed into simplier substances by chemical or physical means
An element is a pure substance that cannot be separated into simpler substances by physical or chemical means. Atoms are the smallest particles in which an element can be divided and still retain its properties.

The substance is a compound, which forms chemical bonds that cannot be physically separated, but only by a chemical change.
