What is the smallest part of the element gold that still retains the chemical properties of gold?

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


What element did glenn seaborg turn into gold?

Glenn Seaborg successfully transmuted bismuth into gold using a particle accelerator in 1980.


Are gold atoms similar to alpha particles?

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.


What is the force of repulsion between an alpha particle and a gold nucleus when the alpha particle passes by the nucleus at a distance of 1pm?

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.


Chemists want to change lead into gold but all failed why?

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.)
