Answers about Gold 1. The term “Gold” as we know it today, actually derives from old English & Germanic origins. 2. The atomic number for gold is Protons, 79 Electrons, 118 Neutrons 4. The element Gold was discovered approx 3000 B.C, it is one of the few elements on the periodic table with no definable individual being credited with the discovery

Answers about Gold 5. Gold is not man made it is found naturally 6. It exists on nearly every continent on Earth 7. its yellowish and comes out looking like a bar. Also, on top of it, there is an "S" with two lines through it vertically 8. No, Gold does not have a smell, and it is also tasteless

Answers about Gold 9 & 10 Gold can be eaten. It is actually found in Gold Schlagger Liquor. Also, gold injections have been used since the 1930's to try and help treat arthritis. therefore I doubt that it is poisonous in any significant way. 11. Dirty gold mining has ravaged landscapes, contaminated water supplies, and contributed to the destruction of vital ecosystems. Cyanide, mercury, and other toxic substances are regularly released into the environment due to dirty gold mining.

Answers about Gold 12. The most common gold compounds are auric chloride (AuCl3) and chlorauric acid (HAuCl4). A mixture of one part nitric acid with three of hydrochloric acid is called aqua regia (because it dissolved gold, the King of Metals). 13. Gold conducts electricity, does not tarnish, is very easy to work, can be drawn into wire, can be hammered into thin sheets, alloys with many other metals, can be melted and cast into highly detailed shapes, has a wonderful color and a brilliant luster

Answers about Gold 14. $1320 per ounce 15. Group Lupac- 11 Group Cas- 1b 16. Solid 17. Melting Point- 1,948°F Boiling Point - 5,173°F 18. Gold is one of the heaviest metals in the world. For example, it is 19,3 times as heavy as water. One cubic meter weights some kilogram.
