4. It has 6 shells of electrons, and there are 78 electrons in about 117 neutrons.
5. Platinum's atomic radius is 2.775 x 10-10 meters.
6. Platinum's properties in pure elemental form can be used as a precious metal, an item used to make jewelry. In other cases it can be used as electrodes in the laboratory. It can also be a alloying agent for various metal products, including fine wires, noncorrosive laboratory containers, medical instruments, dental prostheses, electrical contacts, and thermocouples.
7. There is no abundance in your body since it is highly toxic. Its abundance in the earth's crust is 37 parts per billion by weight. In our universe, its 5 parts per billion.
