Why is copper so unresistant?

Answer 1

Copper is a tough material because, take copper wire for example, you can bend it a lot before it actually fractures and breaks. This is toughness. Toughness is defined as the ability of a material to withstand a sudden impact without fracture. it also refers to a material's ability to withstand bending.

Answer 2

Metals like Iron are said to be more electropositive than copper- that is they tend to react by losing electrons and forming positive ions. So the more electropositive they are the more vigorously they should react to form positive ions. A better method of determining the tendendency of a metal to be oxidised (i.e. lose electrons to form that positive ion) is to connect a sample of the metal in a 1M solution of its ions to a Standard Hydrogen Electrode and read its Standard Reduction Potential from the High Resistance Voltmeter. Metals can then be ordered by their SRP. Some very reactive metals like Alumio not appear to be very reactive at all because they are covered in a thin layer of their oxide, so beware!

Answer 3

Because it is considered an excellent conductor. Electrons flow freely in copper. The only thing superior to copper is gold and silver, but both are very expensive compared to copper.

Answer 4

because copper atoms have only 1 valance electron to add to the electron 'sea' each, so the bonds btween the elctron sea and the now +ve charged atoms is weak

Answer 5

yes
