The smallest unit of life that can exist as a separate entity is a cell.
The smallest unit of Matter that retains the property of an element is the 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.
The smallest unit of an element that is still that element is an atom. Some elements normally exist as molecules, but under some circumstances these can be broken down to individual atoms.
An 'atom' is the smallest unit that ANY element can be divided up into. An 'atom' of silver is the smallest piece of silver that there can be, similarly an 'atom' of oxygen is the smallest bit of oxygen that can be. Thus all elements are made of 'atoms'.
An atom is a particle, the smallest particle that can exist by itself.

There is sufficient chemical driving force to cause most elements to react with other elements into contact with which the elements come.

That's a difficult question to answer, because elements are made of atoms. An atom is the smallest particle of an element that has the properties of that element. Some elements, like the noble gases, can exist as single atoms. Other elements, like oxygen, exist as molecules, such as O2, which is composed of two oxygen atoms covalently bonded to one another. Metal elements are composed of many, many atoms joined by metallic bonding.
The correct spelling is molecule, the smallest component particle of a substance. Molecules can be composed of various elements, or of more than one atom of a single element when they exist naturally in groups (e.g. O2 for dioxygen, O3 for ozone).
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.

Yes, single-celled organisms can exist independently.
