An atom is a particle of matter that uniquely defines a chemical element. An atom consists of a central n u c l e u s that is surrounded by one or more n e g a t i v e l y charged electrons. The n u c l e u s is positively charged and contains one or more relatively heavy particles known as p r o t o n s and n e u t r o n s.
An atom is the smallest unit of matter that retains all of the chemical properties of an element.
For example, a gold coin is simply a very large number of gold atoms molded into the shape of a coin, with small amounts of other, contaminating elements.
