good conductors of heat

. But compared to other metals, gold is a good conductor of heat.

What makes gold so special?

Gold has unique physical chemical characteristics that made it very valuable.

Gold is the most maleable and ductile of all the metals

. … Gold has the highest corrosion resistance of all the metals and it is corroded only by a mixture of nitric and hydrocloric acid. Gold is a noble metal because it does not oxidize.

What does gold smell like?

And though we associate the color gold with so many scents and natural components (honey, sunflowers, wheat, citruses, narcissus, marigolds) gold as a metal

has no detectable smell

. In fact, many people who are suspicious of a gold metal’s integrity will be alerted by a “scent” coming from the metal.

Can gold rust?

Gold

is one of the least reactive elements on the Periodic Table. It doesn’t react with oxygen, so it never rusts or corrodes.

Gold

is unaffected by air, water, alkalis and all acids except aqua regia (a mixture of hydrochloric acid and nitric acid) which

can

dissolve

gold

.
