Electrons in metals are delocalized, the movement is free.

A spoon is a good conductor because it is made of metal, which has a high density of free electrons that can easily move and transfer heat or electricity. This allows heat or electricity to flow through the spoon quickly, making it an effective conductor.
Not all of them are. A metal spoon is a good conductor because it's made of
metal. Plastic or wood spoons are not good conductors, because they're made
of plastic or wood.
Yes, wood is not a good conductor of electricity. Therefore, a wooden spoon will not conduct electricity like metal spoons would.
A spoon is a good conductor of heat and electricity due to its metal composition. Metal materials like stainless steel, which spoons are commonly made of, allow heat or electricity to flow easily through them.
A plastic spoon is a poor conductor of heat. This means that it does not transfer heat efficiently, making it suitable for use in handling hot foods without transferring much heat to the user's hand.
A metal spoon handle gets hot in soup because metal is a good conductor of heat, meaning it can easily transfer heat from the hot soup to the handle. On the other hand, plastic is a poor conductor of heat, so it does not easily transfer heat from the soup to the handle of a plastic spoon. This is why a metal spoon handle will feel hotter to the touch compared to a plastic spoon handle when used in hot soup.
Wood is an insulator. Think about it; when you put a wooden or plastic spoon in boiling water, does it burn your hand? No. This is because it slows the flow of heat from the water to your hand. I do not suggest trying the same thing with a metal spoon, which is a good conductor.
