Assuming that atomic gold is a sphere, as shown above, we can calculate its atomic volume. Atomic volume: VAtom 4 3 R 3 = However, the effective volume of a gold atom is 25% of the unit cell volume, 22 R 3. Effective atomic volume: VAeffective 22 R 3 4 = VAeffective 42 1 2 R 3 =. Name: Gold Symbol: Au Atomic Number: 79 Atomic Mass: 196.96655 amu Melting Point: 1064.43 °C (1337.5801 K, 1947.9741 °F) Boiling Point: 2807.0 °C (3080.15 K, 5084.6 °F) Number of Protons/Electrons: 79 Number of Neutrons: 118 Classification: Transition Metal Crystal Structure: Cubic Density @ 293 K: 19.32 g/cm 3 Color: Gold Atomic Structure. How many electrons does each gold atom gain? How many electrons does each iodine atom lose? What is the total number of electrons that are moved in the oxidation-reduction reaction? Complete the final balanced equation based on the half-reactions. Gold is the chemical element with 79 protons in each atomic nucleus. Every atom containing 79 protons is a gold atom, and all gold atoms behave the same chemically. In principle, we can therefore create gold by simply assembling 79 protons (and enough neutrons to make the nucleus stable).

Gold Atomic
Alternative Titles: Au, aurum
Gold (Au), chemical element, a dense lustrous yellow preciousmetal of Group 11 (Ib), Period 6, of the periodic table. Gold has several qualities that have made it exceptionally valuable throughout history. It is attractive in colour and brightness, durable to the point of virtual indestructibility, highly malleable, and usually found in nature in a comparatively pure form. The history of gold is unequaled by that of any other metal because of its perceived value from earliest times.
