Shown here is a single unit cell of rutile (TiO 2);a top-down view is also provided for additional clarity of atom positions. Titanium atoms are ycllow and smaller; oxygen atoms are blue and larger. If you had to calculate the density of rutile, how many of each atom would you count as being in a single unit cell of rutile?
