Why do metals have high melting and boiling points?

A

Because they have strong metallic bonds that need a lot of energy to be broken.

Q

Why are metals good conductors of electricity?

A

They contain electrons that are free to move in the metal structure, allowing them to carry electricity from place to place.

Q

What is metallic bonding?

A

Metallic bonding is the strong attraction between closely packed positive metal ions and a ‘sea’ of delocalised electrons.
