An element is a substance that has one kind of atom.
A chemical element has only one kind of atom ... atoms of that element.
Examples: Hydrogen, helium, oxygen, carbon, silver, gold, iron, lead, uranium.
A chemical compound has atoms of all of the elements of which it's composed.
Examples: Water, carbon-dioxide, octane, any salt, any sugar, any alcohol, DNA, TNT, DDT.

An element is composed of one kind of atom.
Something that is only one type of atom is an element. There is no name applying to both atom and compound, other than "a pure substance".

Matter with only one particular kind of atom is known as an element. These atoms can either be located individually or combined into larger units. An example of this would be the notion that carbon is an element, because at it's pure substance state it's composed of only carbon atoms.
