This depends on each metal.
Metal atoms become ions when they lose electrons.
It becomes rusty
atomic radii increases from left to right in the periodic table from metal to non metal in the right
The best conductor of electricity is silver, though gold is used more often because it does not oxidize. But of course, copper, silver, and gold are all very close in conductivity. The best conductor of heat is Helium (in its Helium II liquid state), which can conduct heat better than diamond or silver. It should be noted that at temperatures approaching absolute zero the metal lead becomes a superconductor, giving zero resistance to the flow of electricity.
Pure mercury will exhibit superconductivity at 4.2 degrees Kelvin. It was the first superconductive material that H. Kamerlingh Onnes found in 1911.
Electrical conductivity is 6.7 Ms/m (mega-siemens / metre) which is approximately the same as 1010 carbon steel. Technetium, cooled to a few degrees above absolute zero, becomes a superconductor. Please see the links.
what metal that becomes a gas at 892oC
With a superconductor. Even better with a room temperature super conductor, of course you'll have to make hydrogen metal for that.
No, the volume of a metal increases as it is heated. It expands.
Only a few of the materials that have been supercooled have become superconductors, and not all of those are metals. There have even been some organic superconductors discovered.
As a metal becomes colder, it generally conducts electricity more efficiently.
When an acid reacts with a metal why does the mass decrease?
Diamond is formed from Carbon, which is not a metal.
This depends on each metal.
A metal is said to be a superconductor if it has some resistance at room temperature, but when it is brought down to a critical temperature; i.e. to a very low temperature such as 20 K, it loses its resistivity completely. Also, a superconductor expels out any magnetic field inside of it that it had at room temperature, and is not affected by any further field applied to it at its cooler temperature.
A superconductor is a material with extremely low resistance to an electrical current. Many are metals or the like which have been supercooled to temperatures approaching absolute zero. Examples are mercury, lead and tin
