I'd venture to say the electrons themselves. They're so small they don't even exist in a concrete place, they are just in a cloud of places they could be. The nucleus is amazingly small compared to the size of the whole atom, but it still has weight, mostly unlike the electron.
An atom is the smallest recognizable part of an element.
electrons negatively charged, located orbiting outside the nucleus.
an element
The atom is the smallest known particle.
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 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 part of all matter has been identified to be a "quark."
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.

No, an atom is
a subatomic particle
That's an atom of gold. An atom is the smallest representative particle of an element.
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.

The electron is actually the smallest particle. The neutron is the largest particle, followed closely by the proton. The electron is much, much smaller.
