Bonding describes how metallic and non metallic elements of the periodic table exist as elements or combined together to form new compounds with different properties.
Metallic bonding is the bonding found in metals, positive metal ions surrounded by a sea of delocalized electrons.
The Actinides also known as the actinoids are a set of elements in the final period of the periodic table from elements 89 to 103. They are a series of radioactive elements with similar properties.
