Homework Help: Compound vs molecule

  1. Dec 19, 2005 #1
    Different books seem to give different meanings to these terms although they are generally along the same lines.

    One book said that an ionicly bonded atoms such as NaCl cannot be labeled as a molecure and must be called a compound.

    Does this inturn mean that atoms bonded covalently cannot be called a compound and must be called a molecure?

    NaCl is an ionic compound.
    H2O is a molecular compound.

    A molecule of H2O has two H atoms and an O atom covalently bonded; whereas there is no similar kind of singular for ionic compounds because they consist of ions in a lattice structure.
