An atom is a a basic unit of matter which consists of a dense nucleus and a cloud of negatively charged electrons. The nucleus of the atom contains protons(positive charge) and neutrons(neutrally charged).
Interesting facts:
There are approximatley 2 sextillion atoms in a drop of water - imagine how many would be in the ocean. If an atom was the size of a movie theater, the nucleus would be about the size of a postage stamp. A piece of human hair is about one million carbon atoms wide. A speck of dust could contain up to three trillion atoms.
