Strings are indeed very small but I'm going to have to agree with the neutrino answer here. They are so light that they were thought to have no mass until the late seventies (I think).

Little is the correct word, not few! \n\nFew is only used when there are more than one eg FEW people understood your question. Little refers to the smallness of quantity of a single item eg money is a singular noun.

How do you know its small? You must have compared it to another.

Two or more elements combined make a compound. The smallest amount of an element is an atom. The smallest amount of a compound is a molecule. "Chemical" is a term with a wide range of interpretations. Depending on context, a chemical can be an element, a compound, a man-made substance, etc. See ref.

Just about anything small/miniatue is cute...think about it.

Amoeba are among the largest single celled organisms, far larger than any bacteria.  Some amoeba are large enough to be seen without needing a microscope!\n\nBacteria are the smallest living things and mycoplasms are the smallest living bacteria (known as nanobacteria).\n\nIf by creatures you mean animals, then the smallest depends a bit on your definition of "small".  The shortest is probably little Trichoplax adhaerens, which looks a bit like a hairy, multi-cellular amoeba.\n\nThe smallest animal in terms of number of cells is probably some kind of Mesozoa, a set of worms famous for being very short and only a few cells across, so much thinner than Tricoplax and less massive.\n\nThe smallest vertebrate is a species of fish that was just discovered recently, though I forget the name of it, sorry.  :-)\n\nIt's recently been discovered that a few single-celled organisms are, in fact, evolved from animals.  If you would count these as animals, they would be the smallest animals, though that would be merely a technicality.\n\nAll of this applies only to adult forms, of course.  We're all very very small to begin with!

I initially thought bonsai also, but then found that the smallest tree in the world is the dwarf willow. In some places, it grows only two inches (5 cm) tall.

Pretty much anything that is smaller or slower than a lion. This does exclude rhinos, hippos, end elephants.

The smallest bird in the world is generally agreed to be the Bee Hummingbird (Mellisuga helenae) from Cuba which weighs a mere 1.6g or 0.056oz. Shortest wings and body length are not really appropriate measurements because they are disproportionately affected by whether or not the bird is flightless or not and its beak length respectively. Another major contender for smallest bird is the Little Woodstar (Acestrura bombus) from S. America. Both these tiny miracles of life fly very competently. The smallest flightless bird is the Inaccessible Island Rail (Altantisia rogersi). Reaching a mere 12.5cm/5inches in length and weighing 35g/1.45oz this little beauty can only be found in the southern Atlantic Tristan da Cunha Islands.

With the most powerful electron micropscopes scientists can acheive a magnification of 2 million times which will still not allow us to see anything as tiny as proteins as molecules.  The smallest biological material that I can think of is nanobacteria that are 300 *10^-9 m in size but the existance of nanobacteria is still disputed.  The following gallery gives a good idea of the range that normal EM's work in.

I think it's official: Apple's newest (clip) Ipod shuffle is the smallest.

Mass. Even photons have a tiny amount of mass due to relativity.\n\nYou were probably thinking of God or Spirits or something else like that, but mass fits your riddle. Do I get ten points?
