Describe the key properties that rely upon metallic bonding and explain this.

Metallic bonding consists of a strong electrostatic attraction between positive metal cations and delocalised electrons. This arrangement is regular and the attraction is non-directional meaning that layers can easily experience a slip in their layers. As a result, a metal is malleable and can be bent and shaped without breaking.Metals are also electrically conductive. In order to conduct electricity, a material must contain charge carriers that are free to move about. In this case, the delocalised electrons act as free-moving negative charges, allowing for this. A final property to consider is the high melting and boiling point of the metal. The attraction between the ions and the electrons is particularly strong due to the close-packing and regularity of the arrangement of them in the structure.
