He shoot the alpha particle through the gold foil. This experiment resulted that most of the alpha particles passed through the gold foil. However, there were few alpha particles which are deflected back. Rutherford believed that there were the positive charge nucleus. in the center of atom and negative charge electron around the nucleus.

The fcc‐structured Au 42 (TBBT) 26 nanocluster shows more enhanced photoluminescence than the non‐fcc‐structured Au 42 (TBBT) 26 nanocluster, indicating that the fcc‐structure is more beneficial for emission than the … Gold clusters in cluster chemistry are gold-derived materials that can either be discrete molecules or larger colloidal particles. Both types are described as nanoparticles, with diameters of less than one micrometer.A nanocluster is a collective group made up of a specific number of atoms or molecules held together by some interaction mechanism. gold-atom [Au 23(SR) 16] − nanoparticle by a two-step metal-exchange method, which leads to the “resection” of two surface gold atoms and the formation of a new 21-gold-atom nanoparticle, [Au 21(SR) 12(Ph 2PCH 2PPh 2) 2] +, without changing the other parts of the starting nanoparticle structure. This precise surgery of the nanocluster 2015-10-05 2008-11-21 Gold atoms cannot be broken down into anything smaller while still retaining the properties of gold. An atom is composed of two regions: the nucleus, which is in the center of the atom and contains protons and neutrons, and the outermost region of the atom which holds its electrons in orbit around the nucleus, as illustrated in Figure 1.

This is the case for many elements, but not for gold! Freestanding clusters of 20 gold atoms take the shape of a pyramid, researchers have discovered.

1. as many of the atoms passed un deflected he concluded that the atom contained large amount of empty spaces 2. As small number of alpha particles were scattered by a small angle , he concluded that there has to be a small positively charged central mass. 3.the positively charged central mass had to very heavy because the alpha particles did not expel any gold atoms from the foil . and those
