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.
States of Matter are the different forms that elements, compounds and mixtures will exist in as either solids, liquids or gases depending on how close their particles are.
Whilst the general trend that metals are solids and non-metal are gases, liquids and solids hold true and as you progress down the non-metals there are more solids there are some key exceptions.
