An atom is the smallest unit of matter that can enter into a chemical combination.
The smallest unit which maintains the physical and chemical properties of a compound is a molecule if it is a molecular compound, or formula unit if it is an ionic compound.
Single atom, especially if its a hydrogen atom.

An atom is the smallest particle of an element that still has the chemical characteristics of that element
The smallest part of any chemical element that can exist is an atom of that element. The smallest part of a chemical compound that can exist is a molecule of that compound.
An atom. Anything smaller is an atomic particle from which all elements are made.An atom is the smallest particle of an element that has properties of that element.An atom is the smallest unit of an element that retains the properties of that element.
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.
An Atom. An atom contains protons , neutrons and electrons. The number of protons in an atom gives it its characteristics. e.g. Hydrogen has ONE proton. Carbon has SIX protons. et seq/.

The smallest particle in the atom is the electron.

An atom is the smallest particle that comprises a chemical element!
The smallest particle of an element would be an atom. Any smaller and it would not be an element, but something more basic. Atoms are made of Protons, Neutrons, and Electrons. Protons and Neutrons are made of Quarks, Leptons, and Bosons.
The smallest particle of an element is called an atom.
The smallest part of any chemical element that can exist is an atom of that element. The smallest part of a chemical compound that can exist is a molecule of that compound.
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.

That's an atom of gold. An atom is the smallest representative particle of an element.
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.
