Magnesium is a highly reactive metal compared to gold, silver and copper. It will form a magnesium oxide as an outer-shell when it comes to contact with oxygen in the air, and it reacts with water, creating hydrogen gas and fizzing.
They are metals.
I think its made out of gold,sliver,and copper.
gold
Not a meaningful question. Gold coins were made from gold and copper without any silver in them. Silver coins were made from silver and copper without any gold.
gold and copper and zinc and sliver and iron, it can be any of those.
U.S. coins were copper, silver and gold in the 1800's.
Because the British empire in 1805 had a shortage of bullion (gold and silver), copper coins were still produced on a contract-basis at the Soho Mint and the price of copper had risen, making it impractical for them to issue copper coins. This eventually lead to the adoption of the gold standard (rather than the dual gold and silver standard) in 1816 and a complete recoinage of the nation's gold and silver (and later copper) coins.
Copper, Nickel, Silver and Gold
Gold is the least metal reactive in the list, followed by copper, magnesium, and then potassium. Gold is known for its resistance to corrosion and chemical reactions, making it one of the least reactive metals.
The coins are .900 gold & .100 copper and have .12094oz of pure gold.
I would like to sale two bit coins. Gold and copper color
because they wanted them to become gold
