What minerals are in gold?
The primary mineral in gold is native gold, which occurs as nuggets or grains. Gold can also be found in combination with other minerals such as quartz, pyrite, and silver. Impurities like silver, copper, and iron may be present in small amounts in gold deposits.
Does silver contain nickel?
No, nickel is an element. Silver is another element. Neither are alloys, silver only contains silver, nickel only contains nickel. "German silver", which is not actually silver, does contain nickel. It's a silver-colored alloy of nickel, copper and zinc.
Is copper used in bombs?
Yes, copper is commonly used in certain types of bombs as a component of the casing. When the bomb detonates, the copper casing can fragment into small, high-speed pieces that can cause additional damage and injuries.
What elements are used to make brass?
Brass is made primarily of copper (which makes up about 60-90% of the alloy) and zinc (which makes up about 10-40% of the alloy). Small amounts of other elements such as lead, aluminum, and silicon may also be added to improve the properties of the brass.
What does copper contain?
Copper contains copper atoms, which have 29 protons and electrons in their nucleus. Additionally, copper can also contain impurities or other elements in small quantities, such as oxygen, sulfur, or silver.
What electronics have valuable metals in them?

List five alloys of aluminum with their principal components?
Duralumin: Aluminum, copper, and small amounts of manganese, magnesium, and silicon. Aluminum-lithium alloy: Aluminum and lithium with small amounts of copper, magnesium, and zirconium. Magnalium: Aluminum and magnesium with small amounts of copper and manganese. Alnico: Aluminum, nickel, and cobalt with small amounts of iron and copper. Aluminum bronze: Aluminum and copper with small amounts of nickel, iron, and manganese.
Was copper used to make the real silver dollar coin?
"Real" silver dollars issued from 1794 to 1935 contained small amounts of copper to make the metal harder. Pure silver is too soft for use in coins because it would wear out quickly. By the middle of the 19th century the alloy was standardized at 90% silver, 10% copper.
Can someone die from copper in there water?
Small amount of Copper sulphate (CuSO4) is used in water treatment plant to kill algae and bacteria. In small amounts, it is not poisonous. But it can be fatal in large amounts.

Is the Liberty Bell made out of metal?
Yes- it's a mixture of 70% copper, 25% tin, and small amounts of zinc, lead, arsenic, silver, and gold. It is still suspended from the original yoke, constructed of American elm.
