S_A_V [24]

A type of atom can be of any type. Elements are pure chemicals that cannot be converted into more basic compounds by conventional chemical processes.

A chemical element is a substance that cannot be disassembled chemically or physically into simpler substances.

A chemical element is essentially a pure substance that cannot be disintegrated, degraded, or changed into other compounds through physical or chemical methods.
