Ionic bonds break heat
WebTo break the IMF in ice (heat of fusion) requires 6.02 kJ/mol and to break the remaining IMF in the vaporization of water requires 40.7 kJ/mol. All IMF are electrostatic in nature, … WebIn the first one, the metal cations are surrounded by electrons that can move freely between atoms. Metallic bonds are not as strong as ionic and covalent bonds. Metallic bonds are responsible for the main properties of metals, such as ductility, where the metal can be easily bent or stretched without breaking, allowing it to be drawn into wire.
