2nd Answer:
The movement of free electrons is the definition of electricity. Molecules (including atoms) that move about is the definition of heat. The faster they move about (Brownian Motion) the more heat can be measured.
Electrons are not "conductors" of heat.

Why is it a good conductor of electricity a good conductor of heat?
Not all are. The general rule among metals is that the better it is for conducting heat, the better it is at conducting electricity. But for things that are not metals, this is not the rule. Diamonds are astonishingly good at conducting heat, much better than copper, but they are terrible at conducting electricity and are considered to be insulators.
Why are halogen poor conductor of both heat and electricity?
Halogens have 7 valence electrons (electrons in their last shell), this means that they require one more electron to become stable (Octet rule). Electricity and heat are conducted when atoms share electrons by bonding (ionic, covalent, and metallic). Metals are good conductors of heat and electricity because they have free moving electrons. Halogens tend to keep their electrons since they have a -1 charge. As one electron is gained for the halogen atoms (diatomic) become stable, it conducts electricity and heat. However, the conduction of heat and electricity is poor because it barely reacts (only one electron reacts). Compare this to any other element which has a higher charge as (+2, -2, +3, -3, etc.), then the other element will conduct heat and electricity better than a halogen. This is because more electrons are shared / reacted, more conduction of electricity and heat (Heat and electricity are sometimes the result of electron movement, or that electrons carry heat and electricity). Note: A special case is an alkali metal which also has one electron to donate, therefore it has a +1 charge. Alkali metals still conduct electricity and heat because they have free moving electrons (delocalized in a sea of electrons moving freely even without reacting). Basically, metals have their own structure where all the electrons move around freely conducting electricity (therefore its an amazing conductor).
Why conductors conduct heat and electricity while insulators are known as poor conductors?
Conductors conduct heat and electricity well because they have delocalised electrons in their structure. Insulators, on the other hand, do not have delocalised electrons and therefore do not conduct heat and electricity as a conductor, although they do conduct to some extent.
Is wood an insulator or a conductor of heat?
wood is an insulator of heat because its electrons don't allow heat and electricity to flow through them
One material that is used as a conductor and one that is used as an insulator?
A good insulator material is rubber and can block heat and electricity from almost anything. Glass is a good insulator too if you are trying to insulate electricity. Plastic is good as well. Most metals are OK conductors. Copper is very good, and Gold is the best, but it is heavy and expensive.
What does metallic form between?
Metallic bonds are formed within metal atoms. It can be as nuclei in a pool of electrons. These free electrons are responsible for the electricity and heat conducting.
Is aluminum a conductivity?
Yes due to the fact it is a metal and metals have delocalised (free) electrons which allow the electrons to move around the metal conducting heat and electricity easier than non metals
What do poor conductors have trouble doing?
Conducting electricity or heat.
Explain why metals are good conductor of heat?
Metals are especially good at conducting heat because they have electrons in. These are called delocalised electrons which are free moving electrons. Therefore when they gain kinetic energy (heat) they vibrate quicker and can then move around. This means that they can pass on the kinetic energy (heat) more quickly.
What property makes solid good at conducting heat?
Their mobile electrons

Is steel a good conductor of heat and electricity?
Yes. Steel has mobile electrons to conduct electricity and heat.
What similar properties does gold have with certain other elements?
Conducting heat and electricity.
Can you list the 10 best metals at conducting electricity and heat?
Silver or Argentum (Ag)The best conductor of heat and electricity is silver.
What are two things metals are good at conducting?
Depending on the metal, heat and electricity are two main things that metal are good at conducting.
