One material may be a better conductor than another due to its atomic structure, specifically the mobility of its electrons. Materials with more free electrons that are able to move easily will conduct electricity more efficiently. Additionally, the presence of impurities, temperature, and crystalline structure can also impact a material's conductivity.
The presence of water can increase the conductivity of a material because water contains ions that can carry electric current. When water is present, these ions can move more freely within the material, allowing electricity to flow through it more easily. This makes the material a better conductor of electricity when in contact with water.
Astatine is not a good thermal conductor. It is a poor conductor of heat due to its low thermal conductivity, similar to other halogens. This makes astatine a relatively inefficient material for transferring heat.
One example of a material that is a poor energy conductor is wood. Wood is an insulator and does not conduct heat or electricity well because of its low thermal and electrical conductivity properties. This makes it useful for applications where reducing energy transfer is important.
Wood is considered an insulator, not a conductor. Conductors allow the flow of electricity, while insulators inhibit the flow of electricity. Wood's high resistance to electrical current makes it an insulating material.
Aluminum is a conductor of electricity because it has a high electrical conductivity due to its free electrons that can move easily through the material. This makes aluminum a good choice for electrical wiring and transmission lines.

They do it so you will learn the material better and do better in class.
No, germanium is not a better conductor than metals such as copper or silver. Germanium is a semiconductor that has electrical conductivity between that of a conductor and an insulator. It is commonly used in electronic devices for its semiconducting properties.
The acid in the lemon makes it a conductor of electricity.

When current passes through a conductor, the electrons in the conductor collide with the atoms, creating resistance. This resistance causes the electrons to lose energy in the form of heat, which increases the temperature of the conductor.
