Answer 1

Yes there is "purple gold"

See this link: http://www.gold.org/jewellery/news/article/2647

"Containing approximately 80 per cent pure gold, purple gold is created by the chemical reaction that occurs when gold is combined with metals like palladium and aluminium."

"Purple gold is also known as amethyst or violet gold. Gold and Aluminium can be alloyed to form a gold intermetallic compound with the chemical formula AuAl2 (one atom of gold to two atoms of aluminium.)

Answer 3

Any substance will evaporate if you heat it enough. But when I say "enough", I mean 2856*C. To get an idea of that, the surface temperature of the Sun is 5400*C. So yes, it would evaporate, but at the moment we don't have the technology to heat anything to that temperature, especially not on Earth.

Answer 4

if you do find this out let me know.
