Q: Was gold recorded in the 12th Dynasty around 1900 BC? ¶
Q: Is gold measured by troy weight and by grams? ¶
Q: Is gold always richer at the surface of gold-bearing veins owing to the oxidation of accompanying minerals followed by weathering? ¶
A: Yes, and washing of the dust into streams and rivers, where it collects and can be welded by water action to form nuggets.
Q: Is gold Au derivatives? ¶
Q: Is gold found in ores in rock formed from the Precambrian time onward? ¶
Q: Is gold visible to the naked eye? ¶
A: Yes, and in most gold mines the gold is invisible.
Q: Was gold given the name of a unit of currency? ¶
Q: Was gold rooted in its relative rarity? ¶
A: Yes, and easy handling and minting, easy smelting and fabrication, resistance to corrosion and other chemical reactions and its distinctive color.
Q: Is gold attacked by and dissolves in alkaline solutions of potassium or sodium cyanide? ¶
A: Yes, and to form the salt gold cyanide—a technique that has been used in extracting metallic gold from ores in the cyanide process.
Q: Is gold strongly attacked by fluorine at dull-red heat to form gold fluoride? ¶
Q: Is gold further associated with the wisdom of aging and fruition? ¶
Q: Is gold blue? ¶
Q: Is gold approved as a food additive in the EU? ¶
A: Yes, Although the gold ion is toxic, the acceptance of metallic gold as a food additive is due to its relative chemical inertness, and resistance to being corroded or transformed into soluble salts by any known chemical process which would be encountered in the human body.
Q: Is gold of pharmacological value, since elemental gold is inert to all chemicals it encounters inside the body? ¶
A: Yes, Some gold salts do have anti-inflammatory properties and at present two are still used as pharmaceuticals in the treatment of arthritis and other similar conditions in the US. These drugs have been explored as a means to help to reduce the pain and swelling of rheumatoid arthritis, and also against tuberculosis and some parasites.
Q: Was gold often seen as beneficial for the health? ¶
A: Yes, and in the belief that something so rare and beautiful could not be anything but healthy.

A: Yes, as well as radio waves.
Q: Is gold slightly reddish-yellow? ¶
Q: Is gold thought to have formed by the R-process in supernova nucleosynthesis? ¶
A: Yes, but a relatively recent paper suggests that gold and other elements heavier than iron may also be produced in quantity by the collision of neutron stars.
Q: Is gold highly conductive to electricity, and has been used for electrical wiring in some high-energy applications? ¶

Q: Is gold resistant to most acids? ¶
A: Yes, though it does dissolve in aqua regia, a mixture of nitric acid and hydrochloric acid, which forms a soluble tetrachloroaurate anion.
Q: Is gold a transition metal and a group 11 element? ¶
