Factors to consider if question is about compounds/bonding

Answer 1

Structure - simple or molecular?
If simple, does it have a large or small relative molecular mass?
Type of bond - covalent, ionic or none?
Movement of electrons - how many, change in eletronic configuration, charge, any free ions?

THEN
think about struture and type of bonds relate to properties e.g.
strength of intermolecular forces?
amount of energy needed to break bonds or separate molecules?
boiling and melting points?
conductor of electricity?
