  • Why do metals have high melting and boiling points? Quora

    Metallic bonding is the strong attraction between closely packed positive metal ions and a 'sea' of delocalised electrons. The attraction between the metal ions and the delocalised electrons must be overcome to melt or to boil a metal. These attractive forces are strong, so metals have high melting and boiling points.
