Answer
An atom has a small, positively charged nucleus surrounded by orbiting negatively charged electrons.
Explanation
The question asks us to fill in the blanks which involve atomic structure of an atom. An atom has a central part called the nucleus, which is comprised of protons and neutrons. The protons have a positive charge and them along with neutrons impart overall positive charge to the nucleus. The other subatomic particle is the electron which is negatively charged, exists outside the nucleus, and orbits around it, much like planets move around a star in solar system. Hence, an atom has a small, positively charged nucleus surrounded by orbiting negatively charged electrons.
