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.
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.
Solubility is a physical property that determines whether an element or compound will dissolve in a solvent to form a solution
Intermolecular forces are the forces of attraction that exist between covalent compounds holding them together. There are three different types of different strengths.
Hydrogen bonding is the strongest type of intermolecular force that exists between simple covalent compounds and molecules. It exists when the two elements in a covalent bond have a large electronegativity difference such as when hydrogen is bonded to either fluorine, oxygen or nitrogen.
