Sulfide is not a metal, it is composed from the element sulfur, which is a non metal.
Bronze is an alloy that is not metal plated. It is composed of copper and tin.
salt
a metal cation and a nonmetal anion
A metal Surface being ground is a physical change, not a chemical change.
Comets are composed mostly of ice while asteroids are mostly made of rock or metal.
No. The inner core is composed of solid metal, mostly an iron-nickel alloy.
Ceres is an asteroid and is composed mostly from rock, metal and a bit of ice.
The inner planets at made out of rocks because of the sun and the falling rocks.
Gas giants are much bigger, are more distant from the sun, and are composed mostly of gas (particularly methane and ammonia) whereas the terrestrial planets are composed mostly of rock and metal, are closer to the sun, and are smaller.
The spherical solid core of the earth. It is an alloy composed mostly of nickel and iron.
A stapler is composed of mostly aluminum sheet metal, cut and pressed to function, and plastic injection molds.
No, for the reason that the metal from which it is made is not found in that form in nature. A hammer is made from steel. Steel is a man-made metal composed mostly of iron with added carbon to improve the properties of the iron.
It's worth a whole cent. The fingerprint isn't stamped in but was etched when someone handled it with dirty fingers. Over time, the oils from your skin will react with the metal in the coin, actually eating into the surface of the coin, which may make it look like the fingerprint was stamped into the coin. This is considered damage to the coin and can easily make the coin worthless to collectors.

salts
Primarily composed of gas. They have no solid surface. However this is currently in contention... Jupiter may have a surface of Hydrogen metal... but our current technology cannot determine this.
