States of matter are the different forms we find elements, compounds and mixtures in the periodic table as solids liquids and gases.
Intermolecular forces are the weak attractions between molecules that are covalently bonded.
Giant covalent structures exist when many atoms are covalently bonded in a large structure.
Ionic compounds have a number of properties due to their bonding, they are brittle, non conductive as a solid and have high melting and boiling points.
The transition metals is a term given to the group of metals that occupy the centre of the periodic table. They are known as the transition elements as they bridge the gap between group 2 and 3. They are all metals, form coloured compounds and can act as catalysts with variable oxidation states.
