I believe the answer is copper.... you can always ask for the atomic number or search a chart (images) on google. :-)
Based on NEC 250.66- #2 copper or 1/0 aluminum.
Density is an intensive property, not dependent from the size of an object.Density is the ratio between mass and volume.If the coin and the bell have the same chemical composition the density is equivalent.
There was a gold rush, not a copper rush, for one. Also, our nation onced had a gold standard, not a copper standard, for gold is much more valuable. In the old days, scientists tried everything that they could think of to turn rocks and such into gold for a reason, and that reason was the fact that gold in any amount, was worth a fortune! Plus, you never hear of 24 karot copper jewelry, do you? Copper is for wiring and such, as gold is too good of a metal for that.
Brass is a substitutional alloy. Due to the similar size of the two elements copper and zinc which make brass one can not fill the interstitial space between the other elements atoms. This means that it can not be interstitial. The elements are however close in all the necessary aspects to form a substitutional alloy. They are relatively even in size, have the same crytal structure and have similar electronegativities. This allows one element to replace the other which in the case of brass where copper is the solvent, zinc atoms become a substitution for the copper atoms

The size of the British Standard Finger is 12.5mm in diameter by 80mm in length according to the IP codes BS EN 60529 Specification for degrees of protection provided by enclosures (IP code). Hope this is of some help.RegardsShane Gr.
There is no standard size.
The NEC requires that if the intended rating of a circuit corresponds to a standard size breaker then that size breaker must be used. In most instances, "rating of a circuit" means the intended connected load plus 25%. If the intended rating of a circuit does not correspond to a standard size breaker, you can go up to the next standard size without any other adjustments. In most circumstances, besides what I've already stated, a 14 gauge copper wire cannot be connected to a breaker larger than 15 amps, 12 gauge copper to a 20 amp breaker, and 10 gauge copper to a 30 amp breaker.
3/4" BSPP (British Standard Pipe Parrallel). These fit together without binding, and must use a washer to seal.
In standard construction this would require a 15 amp breaker and 14 gauge copper wire.

What is the standard-size large envelope?
The first standard-issue US "pennies" (actually they're cents) were Large Cents struck in 1793. They were about the size of half-dollars.Modern small cents were introduced in 1856. They were never made of pure copper; at various times they were made of copper-nickel, bronze, steel, and (today) copper-plated zinc.
