That's an atom of gold. An atom is the smallest representative particle of an element.
Glenn Seaborg successfully transmuted bismuth into gold using a particle accelerator in 1980.
An alpha particle is the nucleus of a Helium-4 atom; therefore, it has 2 neutrons and 2 protons. A gold atom has... well, much more protons and neutrons, you can look it up if you like. Also, a gold atom normally does have electrons, whereas an alpha particle is just the nucleus (i.e., no electrons). You decide for yourself how "similar" those two are.
The force of repulsion between the alpha particle and the gold nucleus can be calculated using Coulomb's law, given by F = k * (q1 * q2) / r^2, where k is the Coulomb constant, q1 and q2 are the charges of the particles, and r is the distance between them. Given the charges of an alpha particle and a gold nucleus, and the distance of 1pm, the force of repulsion can be calculated to be extremely large due to the proximity of the particles and the high charges involved.
Because they didn't have particle accelerators. It IS possible to change lead into gold using one of those, but only in submicroscopic quantities and it would cost far more than the gold would be worth.Both lead and gold are elements. They are not made of simpler substances that can be chemically recombined to change one into another.(At the subatomic level, they ARE made of simpler substances that can be recombined; that's why the particle accelerator trick works.)

The smallest particle in gold should in fact be gold. Gold is an element, Au, and thus should only contain gold atoms. You could also argue that some subatomic particle is the smallest particle in gold.

The smallest possible particle of gold that can exist is called a gold atom. Gold atoms are the basic units that make up gold and can exist on their own or be part of larger structures.
Correct, due to the massive size of the gold nucleus compared to the size of the incoming particle, the particle will not experience a large deflection in a head-on collision. This is because of the concentrated positive charge in a small space in the gold nucleus that causes a very strong Coulomb repulsion when the incoming particle gets close to it.
