No, gold is around twice more expensive than iridium.
Gold (Au)
Uranium is very common compared to silver (22-40 times more plentiful depending on source) and much more common than gold. Australia & Canada have the largest reserves of the element as well. Iridium in contrast is the rarest solid non-radioactive element in the Earth's crust. Now when comparing the abundance of elements in the universe, uranium is actually much rarer than iridium (which is more common than silver or gold).
Gold, platinum, iridium, and rhodium.
Bauxite ore is the base for aluminium and is more plentiful than gold ore. It is also cheaper to polish to the finished product. Aluminium has many more uses than gold so is readily adaptable to the consumer market. by Ruwayda :)
no,just harder
Osmium and iridium are both heavier than gold.
Should be harder to scratch than gold
iridium osmium platinum plutonium
Iridium is a valuable metal and is rarer than gold or platinum. A search of the internet using "iridium coins" should reveal dozens of sites claiming to have the genuine article.
Iridium is mixed with gold in India to increase the weight of the material, this is a fraud and is illegal
Yes
Because gold is found naturally
Gold is more rare to find!
Lead has a higher atomic number than iridium, which means a lead atom is heavier than an iridium atom. however iridium is denser, therefore if you had a block of iridium and a block of lead,the iridium block would be heavier
Iridium mingles with gold, but for what reason, hardening?
Platinum, iridium, osmium, rhenium, Neptunium,Uranium, and possibly things above Neptunium
No, but Iridium is more valuable.
