# Is water a heterogeneous molecule? [closed]

My question is based upon the statement found here:

an element may be homogeneous on a larger scale, compared to being heterogeneous on a smaller scale. This is known as an effective medium approach, or effective medium approximations.

So, is it acceptable to say that water molecule is a heterogeneous molecule?

• I have never heard of heterogeneous molecule or any similar terminology, but it seems you mean a heterogeneous mixture. – M.A.R. Oct 27 '15 at 21:13

A molecule is homonuclear if it consists of atoms of a single chemical element ($\ce{O2}$). A molecule is heteronuclear if it is composed of more than one element ($\ce{H2O}$). Note that any pure molecule is considered a substance, and it is the combinations of these substances that form mixtures, either homogeneous, heterogeneous, or colloidal.
