3. good conductors of heat

4. high density

5. malleable

6. ductility

2) 1. an electrolyte

2. an exposed metal surface

3. an electron acceptor

3) the lower the level of resistivity,the more electrical conductivity a metal has.copper has also less oxidative than other metals

5) A single-displacement reaction, is a chemical reaction in which one element is replaced by another in a compound

I hope this is help you

Answer 2

Answer:

Here is your answer

•Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).

•Three things are necessary for corrosion to occur: an electrolyte, an exposed metal surface, and an electron acceptor. Corrosion can be prevented by removing one of these conditions. Coating a metal surface with paint or enamel provides a barrier between the metal and the moisture in the environment.

•The lower the level of resistivity, the more electrical conductivity a metal has. Copper has low resistivity, and therefore is an excellent conductor. Copper is also less oxidative than other metals.

•Displacement reactions occur when a metal from the electrochemical series is mixed with the ions of a metal lower down in the electrochemical series. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal. An example can be seen below.

sorry dear don know the fourth one
