Some examples of metals that look like copper include brass, bronze, and rose gold.
Some examples of metals that look like silver include aluminum, stainless steel, and titanium.
Copper and gold look similar, but while gold is yellowish, copper is reddish.
NONE copper is an element and contains only copper - alloys (mixtures of copper combined with other metals) such as brass (copper and zinc) and bronze (copper and tin) both look different and cause the alloys of copper to have different characteristics
nonmetals look like metals but are dull and brittle .
The 1943 US penny reflects the shortage of some metals due to production for the war. Instead of copper, the pennies were made of steel, and are grey in color.
Pure gold is typically a yellow color, but certain alloys of gold can have a reddish or coppery hue. This is achieved by mixing gold with other metals like copper or silver to create different shades of gold. So, while gold itself is not naturally copper-colored, it can be modified to appear that way through alloying.
Bronze is an alloy of Copper and Tin metals. In "pure" form and polished it appears metallic and with a colour ranging from pinkish to yellowish depending upon the proportions of copper and tin in the alloy, very similar to Brass.
All metals are good conductors by their very nature. If you have a piece of metal which appears to not be conducting, maybe it has a layer of clear varnish on it which is preventing a good contact. The copper wire used for winding coils might look like bare copper, for example, but actually has a thin layer of varnish which must be scraped off where an electrical contact is required.
Iron, Cobalt and Nickel (Steel is also magnetic, but it is made up of mostly Iron so this is not a main magnetic metal)
Because they believed they could eventually make gold, and lets face it, who wouldn't want to be able to make gold out of extremely common metals like lead or copper?I think they were fooled by combining molten zinc and copper, because this produces brass, which can look very similar to gold to the naked eye.
Copper oxide appears as a black or dark brown powder after copper has burned.
