Atoms are made of protons, electrons, and neutrons, which are themselves made up of quarks. However, scientists don't have the ability to just 'cut' an atom into smaller pieces, even though it's made of such.
The atom is the smallest known particle.
An atom is the basic unit of matter, consisting of a nucleus composed of protons and neutrons, surrounded by electrons in orbitals. It is the smallest particle of an element that retains the chemical properties of that element. Atoms combine to form molecules and compounds and are the building blocks of everything in the universe.
This particle is the atom.
It is an atom.
A molecule is the smallest particle of a "compound" being that compounds are made up of more than one atom. The smallest particle of any "chemical element" that retains its properties would be the atom.
The atom.
The atom is the smallest known particle.
The smallest particle of an element is called an atom.

The smallest particle in the atom is the electron.
An atom is the smallest particle of a substance.
A molecule is the smallest part of a compound that still retains the properties of said compound. As the atom is the smallest particle of an element into which it can be divided and still retain all the properties of that element, the molecule is the atom's analog for a compound.
An atom is a particle, the smallest particle that can exist by itself.
An iron atom is the smallest iron particle that still has the properties of iron.
An atom is the smallest particle of an element that can be uniquely identified as that specific element.Note that this question is different from asking "What is the smallest particle in an atom?" (see related question below). Atoms are composed of smaller particles (protons, electrons, and neutrons), but the smallest thing that has the identity of a specific element is the atom.The smallest particle of an element that still retains all that element's properties is called an ATOM.
An ATOM!!!! An atom can be sub-divided in to protons, neutrons, and electrons.
