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.
Some elements (such as oxygen) form molecules containing two or more atoms, and these molecules have different chemical characteristics. However, it is always possible to break down these molecules into single atoms of the element, or conversely to from these molecules from single atoms.
The smallest particle is currently believed to be the quark. We've never seen one, and our currently understanding of particle physics suggests that they don't exist singly, so we probably ever will.
That is, until our understanding of basic physics changes - again - which it has been doing every 15 years or so since the 1900's. Back then, the "smallest" particle was believed to be the electron.
An atom is the smallest particles of an element.
An atom is the smallest particle of an element that still has the chemical characteristics of that element
An Atom
It is an atom.
A molecule.
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.
The smallest particle of an element is called an atom.
An atom is the smallest particle of an element that still has the chemical characteristics of that element
a quark or if you mean the smallest element hydrogen
This particle is the atom.
If it is an element, then the smallest particle that retains the characteristics of the element is an atom. If it is a diatomic element, then the smallest particle that retains the characteristics of the element is a molecule. If it is a molecular compound, then the smallest particle that retains the characteristics of the compound is a molecule. If it is an ionic compound, the smallest particle that retains characteristics of the compound is a formula unit.
An atom is the smallest particle that is still recognisably the element
The smallest particle in the atom is the electron.
The smallest particle of an element that has the properties of that element is called an atom.

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.
This particle is called atom.
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.
