A pure substance has only one kind of particle. Sulfur is an example of a pure substance.
A substance that is composed of only one kind of matter is called an element. The smallest particle of an element is called an atom.
A single atom of hydrogen-1 is the smallest particle of hydrogen. A hydrogen-1 atom contains only one proton and one electron, and is the simplest atom.
The answer is likely supposed to be "an element", but ANY chemical substance contains only one type of particle, whether it is an element (atoms) or a compound (molecules). It is only combinations of elements or compounds (alloys, solutions, mixtures) that contains multiple types of particles.

A compound.
By definition, an Element contains only one kind of atom - atoms of that element. If it has more than one kind, it is a compound, not an element.
