How small is an atom?

Answer 1

Think of it this way:

Remember the last time you went to the beach and just picked up some sand. There is probably more atoms in one grain of sand than there is grains of sand on that entire beach.

Or think about it this way:

Go get a needle. Now stare at the needle's head (the place where you thread it) and think, If you were to give every person in the United States of America one penny for every atom there is making up that needle head, everybody you gave a penny to would have about 20 billion dollars.

Or maybe this way:

There are about 5 million atoms in the period at the end of this sentence.

Atoms make up elements, and elements make up certain things. Therefore, there is nothing smaller than an atom. Scientists are still working on developing a microscope that can catch just the smallest glimpse of an atom.
