Can sodium chloride be categorised as a giant molecular structure

  1. Apr 8, 2012 #1
    I was attempting this question where I had to say which, out of graphite, diamond and sodium chloride represent a giant molecular structure? The answer is only the first two. Why is the latter excluded?

    Stemming from that, a molecule is defined as two or more atoms covalently bonded. By definition, ionic bonds are excluded.
