    I've tried searching this question on Google, but have not received anything useful. Could someone please explain how or suggest where I look?

    Like you, I could not find an easy answer to this very broad question on the web.

    I'm tempted to say that molecular properties arise principally from the arrangement of the electrons in the outermost, "bonding" or "valence", shell of the atoms making up the molecule. This is on the basis that chemistry is the science of chemical bonding. But of course the nuclei of the atoms of the molecule also affect the properties, in that the possible arrangements of outer shell electrons - and their energy levels - are determined by the charge on the nucleus - and also in some properties the mass of the nucleus plays a role.

    Perhaps others may care to add to this, but it's a start.
