## Chemistry: The Science in Context (4th Edition)

To name a binary compound made of two or more nonmetals, we keep the name of the first element as-is and add a prefix to this element's name only if there is more than one atom of this element in the compound. We always add a prefix to the second element (or polyatomic ion) to denote how many atoms of this particular element are in the compound, and we change the ending of the element's name to $-ide$. (a) nitrogen trioxide (b) dinitrogen pentoxide (c) dinitrogen tetroxide (d) nitrogen dioxide (e) dinitrogen trioxide (f) nitrogen monoxide (g) dinitrogen monoxide (h) tetranitrogen monoxide
