Question

which is not a good conductor of electricity.
a) mercury
b) copper
c) plastic
d) aluminum ​

Answer 1

Answer:

d) aluminum is not good conductor of electricity

Answer 2

Answer:

c) Plastic

Explanation:

Mercury is a poor conductor of heat, but a fair conductor of electricity. Mercury has a unique electron configuration which strongly resists removal of an electron, making it behave similarly to noble gas elements. As a result, mercury forms weak bonds and is a liquid at room temperature.

Copper is a metal made up of copper atoms closely packed together. ... The electrons can move freely through the metal. For this reason, they are known as free electrons. They are also known as conduction electrons, because they help copper to be a good conductor of heat and electricity.

Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators. ... Electricity requires a complete "loop" for current to flow.

Conductors consist of materials that conduct electric current, or the flow of electrons. Nonmagnetic metals are typically considered to be ideal conductors of electricity. The wire and cable industry uses a variety of metal conductors, but the two most common are copper and aluminum.
